SIMON II, sire de Lalaing, chevalier, époux d'Alexandra DE LESDAING, fille du chevalier N... de Lesdaing et de Marguerite de N....

II améliora sa «ville » au point de vue de la défense (Preuves, n° XI).
En 1242, il céda a l'abbaye d'Anchin son moulin a eau banal de Lalaing, en se réservant sur lui une rente en blé, qu'il reprit en fief de l'abbé (Preuves, nosX et XI).

Il fit, en 1243, une fondation au profit des pauvres de sa terre (Preuves, n° XII).

Dans un acte dû mois de janvier 1256 (vieux style), il est question des hoirs (liberi) de Lalaing, qui avaient une seigneurie à Roucourt (2). ...
(1) En avril 1244, domina Margaritade Lesdaing, c'est-à-dire :
dame Marguerite de N veuve de N.... de Lesdaing, chevalier,
détenait, à titre précaire, douze muids de terreau terroir d'«Hasencourt " (Azincourt, à Emerchicourt.; comme Gilles, sire de Denaing, chevalier, vendait six muids de terre, au même terroir, il. assigna en échange, à Gila, sa femme, pour garantie de si dot, sept muids de terré à lui appartenant, à prendre dans les douze « que tient à présent dame Marguerite de Lesdaing " (Arch. départ, fonds d'Anchin).

En 1270, Nicolas II évoque le souvenir de feu « medame Margeritain de Lesdaing, me thdên, " la mère de sa mère (Hautcoeur, Cartul, de Flines, j, p. 182, Lille, 1873, in-3°).

C'était le 19 octobre qu'on chantait, ; en l'église de Lalaing, « l'obit de Met Simon de Lalaing, jadis seigneur dudit Lalaing et de Sepmeries (3), et de dame Alexandre, son espeuze, lequel seigneur gist en l'abbaye de Flines (4), et ladite dame, devant le crucefix, soubz ung viel marbre , en l'église dudit Lalaing » (5).

L'auteur de l'armorial auquel a été donné le titré mensonger de « Grand Tournoy de Compiègne de l'an 1238, au mois de février », a mis notre Simon II en compagnie de "Jehan d'Avesnes,comle de Hainaut » (1280-1304)! D'après le Ms. de cet armorial qui a servi à la publication de M. E. de Barthélémy (Le Tournoi de Compiègne, Saint-Quentin, 1873, in-8°, page 16), le sire de Lalaing figurerait le 141e et serait ainsi désigné : « Simon, sr de Salaincg: De gueule à 10 losanges d'argent accolées et posées en fasce 3,3,3, 1. »
Simon II laissa au moins deux fils :
1° Nicolas, qui suit.
2° Simon de Lalaing, auteur de la branche de Semeries, qui suivra.

(1) la dame de Lalaing était veuve en 1252 et administrait la seigneurie pour ses enfants mineurs (Preuves, n° XIII).
(2) Archives départ.; fonds de l'abbaye des Prés de Douai.
(3) Simon II ne fut pas sire de Sepmeries, mais bien son fils ca det Simon, à couse de sa femme.
(4) Peu probable, vu la date de la mort de Simon II, vers 1230, quand l'abbaye était encore à Orphies. On aura confondu ceseigneur avec son petit-fils Simon III.

VI. SIMON II, sire of Lalaing, knight, husband of Alexandra DE LESDAING, daughter of knight N... de Lesdaing and Marguerite de N....

He improved his "city" from the point of view of defense (Preuves, n° XI).
In 1242, he ceded to the abbey of Anchin his common water mill of Lalaing, reserving for himself a rent in wheat, which he took back in fief from the abbot (Preuves, nos. X and XI).

In 1243, he made a foundation for the benefit of the poor of his land (Preuves, n° XII).

In an act due January 1256 (old style), it is question of the heirs (liberi) of Lalaing, who had a seigneury in Roucourt (2)...
(1) In April 1244, domina Margaritade Lesdaing, i.e. :
lady Marguerite de N widow of N.... de Lesdaing, knight,
held, on a precarious basis, twelve muids of land in the soil of "Hasencourt" (Azincourt, in Emerchicourt); as Gilles, lord of Denaing, knight, sold six muids of land, in the same soil, he assigned in exchange, to Gila, his wife, as a guarantee of his dowry, seven muids of land belonging to him, to be taken from the twelve "that Lady Marguerite de Lesdaing holds at present" (Arch. départ, fund of Anchin).

In 1270, Nicolas II evokes the memory of late "medame Margeritain de Lesdaing, me thdên," the mother of his mother (Hautcoeur, Cartul, de Flines, j, p. 182, Lille, 1873, in-3°).

It was on October 19 that one sang, in the church of Lalaing, "the obit of Met Simon de Lalaing, formerly lord of the aforementioned Lalaing and Sepmeries (3), and of lady Alexandre, his espeze, which lord lies in the abbey of Flines (4), and the aforementioned lady, in front of the crucifix, under an old marble, in the church of the aforementioned Lalaing" (5).

Flines Abbey from the south, in the cartulary of the Duke of Croÿ (probably 1603)

The author of the armorial to which was given the false title of "Grand Tournoy of Compiègne of the year 1238, in the month of February", put our Simon II in company of "Jehan d'Avesnes, comle de Hainaut" (1280-1304)! According to the Ms. of this armorial which was used for the publication of Mr. E. de Barthélémy (Le Tournoi de Compiègne, Saint-Quentin, 1873, in-8°, page 16), the lord of Lalaing would appear the 141st and would be thus indicated: "Simon, sr de Salaineg: Of gueule with 10 lozenges of money joined and posed in fess 3,3,3, 1.
Simon II left at least two sons:
1° Nicolas, who follows.
2° Simon de Lalaing, author of the branch of Semeries, who will follow.

(Curator note: the term “money” is a frequent mistranslation in heraldry. Argent is a word meaning silver as a tincture, silver was used as money, hence the mistranslation ten lozenges of money = ten lozenges of silver))

(1) The lady of Lalaing was a widow in 1252 and administered the seigneury for her minor children (Preuves, n° XIII).
(2) Archives départ; funds of the abbey of the Pres de Douai.
(3) Simon II was not lord of Sepmeries, but his son ca det Simon, on the death of his wife.
(4) Unlikely, given the date of Simon II's death, around 1230, when the abbey was still at Orphies. This lord will have been confused with his grandson Simon III.

Of Simon II we know very little. He would have died but his marriage to Alexandra de Lesdaing allows the entry of the land of Semeries into the family possessions. Knighted in 1242, he is described as a fiefdom man of the Lady of Bouchain in Ostrevent. He attends the courses and the many tournaments of chivalry. In February 1238, he was present at the Compiègne tournament organized by Saint Louis on the occasion of the marriage of his brother, Robert d'Artois (19). He had three sons: Nicolas who succeeds him, Simon the youngest who will give birth to the branch of Semeries. As for Gillis, he is cited around 1285 by Jacques Bretel. He is one of the guests of the Comte de Chiny, who came to the Chauvency-le-Château tournament, along with the Hondschoote, Ligne, Haussy, Montigny and the sons of the Comtes de Hainaut and Flandres. He marries Magdeleine de Duras. The couple have a son, Robert, Lord of Haudion.

(19) He married Mahaut, daughter of Henri II, Duke of Brabant and Lorraine.

SIMON [II] de Lalaing (-[19 Oct]

---

, before 1252, bur Flines). The primary source which confirms his parentage has not been identified. Seigneur de Lalaing. The necrology of Lalaing records the death 19 Oct of “Simon de Lalaing jadis seigneur dudit Lalaing et de Sepmeries et de dame Alexandre son espeuze, lequel seigneur gist en l’abbaye de Flines et ladite dame...en l’église dudit Lalaing”[388]. m ALEXANDRA de Lesdaing, daughter of --- de Lesdaing & his wife Marguerite --- (-after 1252, bur Lalaing). The Catalogue des Lalaing names “Alexandra de Lesdaing, fille du chevalier N--- de Lesdaing et de Marguerite de N” as the wife of Simon [II], noting that she administered her deceased husband’s estates in 1252 on behalf of her minor children[389]. Simon [II]’s mother-in-law is named in the following document: “Nicolas sires de Lalaing chevaliers” donated revenue to Flines, for the souls “me...feme Agniès dame de Lalaing...medame Margeritain de Lesdaing me thaïen”, by charter dated Apr 1270[390]. The necrology of Lalaing records the death 19 Oct of “Simon de Lalaing jadis seigneur dudit Lalaing et de Sepmeries et de dame Alexandre son espeuze, lequel seigneur gist en l’abbaye de Flines et ladite dame...en l’église dudit Lalaing”[391]. Simon [II] & his wife had [three or more] children:
a) NICOLAS [II] de Lalaing (-8 Mar

---

, after 1285, bur Lalaing). “Nicolas sires de Lalaing chevaliers” donated revenue to Flines, for the souls “me...feme Agniès dame de Lalaing...medame Margeritain de Lesdaing me thaïen”, by charter dated Apr 1270[392]. The necrology of Lalaing records the death 8 Mar of “messire Nicole de Lalaing” who was buried in the church[393]. m AGNES de Willerval, daughter of --- (-after Oct 1274). “Nicolas sires de Lalaing chevaliers” donated revenue to Flines, for the souls “me...feme Agniès dame de Lalaing...”, by charter dated Apr 1270[394]. “Nicolas de Lalaing” and his wife “Agnes damme de Huillerval” confirmed the donation of revenue to the chapel of “Izel-lez-Esquerchin” by charter dated Oct 1274[395]. [Goethals notes that “selon la généalogie de la famille” [unspecified] Nicolas de Lalaing married firstly “Aldegonde fille du seigneur de Chiévres” and secondly “Isabelle fille du châtelain de Bapaume, seigneur de Beaumez”[396]. This information is contradicted by the two charters quoted above. Maybe it refers to another Nicolas de Lalaing.] Nicolas [II] & his wife had [four] children:
i) SIMON [III] de Lalaing (-2 May 1333, bur Flines). The primary source which confirms his parentage has not been identified. The Catalogue des Lalaing notes that early genealogists recorded “Otton de Lalaing...Isabeau de Saarbruck” as the parents of Simon [III], suggesting that this was based on the tomb of Gille de Lalaing Abbess of Flines which includes the arms of Saarbrücken among her huit quartiers, commenting that the Flines epitaphs “avaient étés refaites” in the early 16th century and that in any case this blason was not included in the epitaph of Simon [III] himself[397]. The poem Les Tournois de Chauvenci records “Simars de Lalain” among those participating in tournaments at Chauvency, dated to 1285[398]. “...Simons de Lalaign chevalier...honme de le contei de Haynau” certified having seen an agreement terminating a dispute between Guy Count of Flanders and Jean Comte de Hainaut, by charter dated 21 May 1295[399]. A memoire concerning Ostrevent, presented to Philippe VI King of France and probably dated to [1338], records that “messire Symon de Lalaing, peres au seigneur qui à présent y est” was suspected of having killed “le seigneur d’Ynmer son oncle”, and was pursued in justice by “madame de Haynaut, mere à monseigneur de Beaumont qui ores est” but “purgié du fait” at Saint Quentin[400]. An epitaph at Flines records the burial of “noble homme Simon jadis sire de Lalaing” who died “le jour de Sainte-Croix” May 1333[401]. m MATHILDE d’Aspremont, daughter of GEOFFROY [III] Seigneur d’Aspremont & his wife Isabelle de Quiévrain (before 1302-Beaumont Convent, Valenciennes 1373). Heiress of Quiévrain. Her parentage and marriage are suggested by her husband’s descendants inheriting Quiévrain, which was held by her mother. They are confirmed by the following document: a charter dated 21 Dec 1346 records that, after the death of “Joffroit d’Aspremont chevalier signeur de Kieurechin” his heirs in Quiévrain were “freres et soers...Henri...eveske de Vredun, medame Mehaut de Lalaing se sereur, madame Alliennor d’Aspremont dame de Fontaines leur soer et monsigneur Joffroit de Saint Disier chevalier”[402]. Nicolas [III] Seigneur de Lalaing certified a charter dated 1300 “verifiyée de bouche par nostre...mere dame de Lalaing et de nos...cousin monseigneur Taillefer de Rosen” by charter dated 20 Mar 1366 (O.S.), sealed by himself and by “notre...fil Colart de Lalaing chevalier signour de Hordaing et seneschal d’Ostrevant...no...cousin monseigneur Jehan de Mortaigne chevalier signeur de Potelles”[403]. The Catalogue des Lalaing records that she became a nun at Beaumont, Valenciennes where she died in 1373, without citing the primary source on which this information is based[404]. Simon [III] & his wife had [ten] children:
(1) NICOLAS [III] de Lalaing (-[20 Mar 1367/4 Jun 1369]). “Collart Sire de Lallaing...”, for himself and on behalf of “ses trois sœurs Florence, Marie et Jeanne”, acknowledged receipt of payments due from “Isabiaus de Kievraing Dame de Spremont” connected with the marriage of “Simon Sgr de Lallaing son pere et de sa mere” by charter dated end-Dec 1338[405].
- see below.
(2) SIMON de Lalaing (-13 Sep 1386, bur Beaumont, Valenciennes). A charter dated 21 Dec 1346 records that “Nicollon signeur de Lalaing sen aisnet fil chevalier” sold property with the consent of “...monsr. Symon de Lalaing, monsigneur Jehan dit Sanson de Lalaing chlrs, freres audit monsr de Lalaing...”[406].
- see below, SEIGNEURS de QUIEVRAIN
(3) JEAN “Sanson” de Lalaing (-after 21 Dec 1346). A charter dated 21 Dec 1346 records that “Nicollon signeur de Lalaing sen aisnet fil chevalier” sold property with the consent of “...monsr. Symon de Lalaing, monsigneur Jehan dit Sanson de Lalaing chlrs, freres audit monsr de Lalaing...”[407].
(4) [ISABELLE de Lalaing (-[Aug 1326/Dec 1338]). The testament of “Isabeau dame d’Aspremont et de Quévrain”, dated [early Aug] 1326, bequeathed property to “Isabeau de Lalaing cordelière en Verdun...nre...fille Felicitas”[408]. It is likely that the testator bequeathed property to Isabelle as her oldest granddaughter at the time. If that is correct, her absence from the Dec 1338 charter, which names her sisters, suggests that she was deceased at the time.]
(5) [BEATRIX de Lalaing (-[4 Apr 1336/Dec 1338]). Nun. The codicil of “Isabeau dame d’Aspremont et de Quévrain”, dated 4 Apr 1336, bequeathed property to “suer Juliane et suer Jehanne d’Aspremont mes filles, suers de led. eglise de Biaumont, à suer Beatrix de Lallaing, à suer Katherine dou Wés, à Marie et à Ysabiel suers as enfans de Wargni”[409]. Her absence from the Dec 1338 charter, which names her sisters, suggests that, assuming that Beatrix was the testator’s granddaughter, she had died before that date.]
(6) FLORENCE de Lalaing (-13 Aug 1380, bur Berelles). “Collart Sire de Lallaing...”, for himself and on behalf of “ses trois sœurs Florence, Marie et Jeanne”, acknowledged receipt of payments due from “Isabiaus de Kievraing Dame de Spremont” connected with the marriage of “Simon Sgr de Lallaing son pere et de sa mere” by charter dated end-Dec 1338[410]. A charter dated 21 Dec 1346 records that “Nicollon signeur de Lalaing sen aisnet fil chevalier” sold property with the consent of “...Gillion de Reumont et demisielle Florence sa femme, demisielle Margherite de Lalaing canoinnesse de Malboege, demisielle Marie de Lalaing canoinesse de Niuielle, et demisielle Gille de Lalaing, sereurs audit signeur de Lalaing”[411]. m ([Dec 1338/Dec 1346]) GILLES de Reumont, son of --- (-bur Berelles).
(7) MARGUERITE de Lalaing (-after 21 Dec 1346). Canoness at Maubeuge: a charter dated 21 Dec 1346 records that “Nicollon signeur de Lalaing sen aisnet fil chevalier” sold property with the consent of “...Gillion de Reumont et demisielle Florence sa femme, demisielle Margherite de Lalaing canoinnesse de Malboege, demisielle Marie de Lalaing canoinesse de Niuielle, et demisielle Gille de Lalaing, sereurs audit signeur de Lalaing”[412].
(8) MARIE de Lalaing (-after 21 Dec 1346). “Collart Sire de Lallaing...”, for himself and on behalf of “ses trois sœurs Florence, Marie et Jeanne”, acknowledged receipt of payments due from “Isabiaus de Kievraing Dame de Spremont” connected with the marriage of “Simon Sgr de Lallaing son pere et de sa mere” by charter dated end-Dec 1338[413]. Canoness at Nivelle: a charter dated 21 Dec 1346 records that “Nicollon signeur de Lalaing sen aisnet fil chevalier” sold property with the consent of “...Gillion de Reumont et demisielle Florence sa femme, demisielle Margherite de Lalaing canoinnesse de Malboege, demisielle Marie de Lalaing canoinesse de Niuielle, et demisielle Gille de Lalaing, sereurs audit signeur de Lalaing”[414].
(9) JEANNE de Lalaing (-[end-Dec 1338/21 Dec 1346]). “Collart Sire de Lallaing...”, for himself and on behalf of “ses trois sœurs Florence, Marie et Jeanne”, acknowledged receipt of payments due from “Isabiaus de Kievraing Dame de Spremont” connected with the marriage of “Simon Sgr de Lallaing son pere et de sa mere” by charter dated end-Dec 1338[415]. Her absence from the 21 Dec 1346 charter which names her sisters suggests that Marie was deceased at the time. Another possibility is that “Jeanne” was the same person as the daughter named “Gille” in the later document.
(10) GILLE de Lalaing (-16 Mar 1388). A charter dated 21 Dec 1346 records that “Nicollon signeur de Lalaing sen aisnet fil chevalier” sold property with the consent of “...Gillion de Reumont et demisielle Florence sa femme, demisielle Margherite de Lalaing canoinnesse de Malboege, demisielle Marie de Lalaing canoinesse de Niuielle, et demisielle Gille de Lalaing, sereurs audit signeur de Lalaing”[416]. Abbess of Flines 1363[417].
ii) [GILLE de Lalaing (-1356). Hautcœur records Gilles as the daughter of Nicolas [II] Seigneur de Lalaing[418]. The primary source which confirms this affiliation has not been identified. Abbess of Flines 1356.]
iii) [--- de Lalaing . Her parentage and marriage are suggested by the following document: Nicolas [III] Seigneur de Lalaing certified a charter dated 1300 “verifiyée de bouche par nostre...mere dame de Lalaing et de nos...cousin monseigneur Taillefer de Rosen” by charter dated 20 Mar 1366 (O.S.), sealed by himself and by “notre...fil Colart de Lalaing chevalier signour de Hordaing et seneschal d’Ostrevant...no...cousin monseigneur Jehan de Mortaigne chevalier signeur de Potelles”[419]. m --- de Rosen, son of ---.]
iv) [--- de Lalaing . Her parentage and marriage are suggested by the following document: Nicolas [III] Seigneur de Lalaing certified a charter dated 1300 “verifiyée de bouche par nostre...mere dame de Lalaing et de nos...cousin monseigneur Taillefer de Rosen” by charter dated 20 Mar 1366 (O.S.), sealed by himself and by “notre...fil Colart de Lalaing chevalier signour de Hordaing et seneschal d’Ostrevant...no...cousin monseigneur Jehan de Mortaigne chevalier signeur de Potelles”[420]. m --- de Mortaigne, son of ---.]
b) SIMON de Lalaing (-[26 Apr/20 Sep] 1300, bur Semeries). The Catalogue des Lalaing records his parentage without citing the corresponding primary source[421]. Seigneur de Semeries, de iure uxoris. m JEANNE de Roisin Dame de Semeries, daughter of JEAN de Semeries & his wife --- (-after Mar 1301). The Catalogue des Lalaing notes that Semeries is now known as “Sepmeries, village situé entre Valenciennes et Le Quesnoy...[%C3%A0 ne pas] confondre avec Semeries près d’Avesnes”[422]. “Jehenne dame de Semeries et...Jehan sen ainsney fill et sen hoir chevalier” settled disputes with Valenciennes Saint-Jean by charter dated 20 Sep 1300[423]. “La dame de Semeries [...Jeanne] et son fils aîné messire Jehan chevaliers” built a chapel at Valenciennes Saint-Jean, in memory of “monsegneur Symon de Lalaing chevalier marit jadis à le dite dame et pere à monsegneur Jehan devant dit”, by charter dated Mar 1300 (O.S.)[424]. Simon & his wife had [four or more] children:
i) JEAN de Lalaing (-after 1308). Seigneur de Semeries. According to Goethals, Jean was the son of Nicolas de Lalaing[425], but the following documents show his correct parentage. “Jehenne dame de Semeries et...Jehan sen ainsney fill et sen hoir chevalier” settled disputes with Valenciennes Saint-Jean by charter dated 20 Sep 1300[426]. “La dame de Semeries [...Jeanne] et son fils aîné messire Jehan chevaliers” built a chapel at Valenciennes Saint-Jean, in memory of “monsegneur Symon de Lalaing chevalier marit jadis à le dite dame et pere à monsegneur Jehan devant dit”, by charter dated Mar 1300 (O.S.)[427]. “Messire Jean de Lalaing sire de Semeries chevalier et Pierre Percheval son frère” granted property to “Margritain de Vicogne, jadis femme Jean de Vicogne” by charter dated 1308[428].
ii) PIERRE dit Perceval de Lalaing (-after 1333). “Messire Jean de Lalaing sire de Semeries chevalier et Pierre Percheval son frère” granted property to “Margritain de Vicogne, jadis femme Jean de Vicogne” by charter dated 1308[429]. Froissart names “messire Perceval de Semeries” among the Hainaut nobles who supported Edward III King of England in 1326 [1327/28?][430].
iii) [--- de Lalaing . The Catalogue des Lalaing says that Beatrix was the son of Pierre dit Perceval de Lalaing[431]. The 6 Jun 1371 charter quoted below confirms that she was the nephew of Jean de Lalaing, son of Simon de Lalaing and his wife Jeanne de Semeries. Pierre is the couple’s only other recorded son, but there is no guarantee that Beatrix’s father was not another otherwise unrecorded son. m ---.] --- & his wife had one child:
(1) BEATRIX de Lalaing (-9 May 1376, bur Beaumont, Valenciennes). Brassart names Beatrix as daughter of Nicolas [III] Seigneur de Lalaing[432]. According to Goethals, Beatrix was the daughter of Jean de Lalaing[433]. The reference to Semeries in the following documents indicates her correct family origin. “Bietris de Lalaing castellaine de Saint-Omer et dame de Semeryes” confirmed the foundation made by “no...taie de boinne memoire me dame Jehenne jadis dame de Semeryes et messire Jehans ses aisnés fils et hoirs nos...oncles” for the soul of “monsr Symon de Lalaing chevalier no taion” by charter dated 6 Jun 1371[434]. An epitaph at Valenciennes Saint-Jacques des Sœurs noires records the burial of “Beatrix de Lalaing châtelaine de Saint-Omer comtesse de Fauquemberghe et dame de Semeries, jadis espeuse à...Floris de Beaumont chastelain de Saint-Omer, comte de Fauquemberghe, seigneur de Beaurieu et de Semeries” who died 9 May 1376[435]. m FLORENT Châtelain de Beaumont, son of BAUDOUIN Châtelain de Beaumont & his wife Mathilde de Saint-Omer (-[22 Jun 1364/20 Jan 1365]). Châtelain de Saint-Omer 1364.
iv) [--- de Lalaing . The Catalogue des Lalaing records other members of the Lalaing/Semeries family who were named in documents dated in the late 14th/first half 15th century, presumably descended from a younger son or sons of Simon de Lalaing and his wife[436].]
c) [--- de Lalaing . The Catalogue des Lalaing records members of a Lalaing/Laidang family who were named in documents dated in the mid-14th/early 15th century, presumably descended from a younger son or sons of Simon [II] de Lalaing and his wife Alexandra de Lesdaing[437].]
