[BILLUNG] .

The Chronica Principum Saxoniæ names "vir…nomine Bilingus" as father of "Hermannum"[196], although the accuracy of this statement is not known. The name of the father of the brothers Amelung, Wichmann [I] and Hermann Billung has not so far been found in any other source. The possibility that some or all of them were uterine brothers cannot be excluded.

m ---. The name of [Billung]'s wife is not known.

[Billung] & his wife had [six] children:

1. AMELUNG (-5 May 962). Bishop of Verden 933. The Annalista Saxo records the death in 962 of "Amalungus Fardensis episcopus…frater Herimanni ducis"[197]. Thietmar also records that Amelung Bishop of Verden, "the duke's [Hermann Billung] brother", died on 5 May "at a good old age"[198].

2. WICHMANN [II] (-23 Apr 944). Widukind names "Wichmanni fratris sui [=Herimannum]", when recording his rebellion against King Otto[199].

3. HERMANN [Billung] ([905/10]-Quedlinburg 27 Mar 973, bur Lüneburg St Michael).

• Graf in Wetigau 940.
• Procurator of the king in Saxony 953, 961 and 966.
• Graf in dem Gauen Tilithi und Marstem 955.
• Markgraf 956
• Dux in Saxony 965.
• He founded St Michaeliskloster at Lüneburg.

m firstly ODA, daughter of --- (-15 Mar ----).

m secondly HILDESUIT, daughter of ---.

Duke Hermann & his [first/second] wife had five children.

4. [BRUNO ([905/15]-after 16 Nov 958, maybe after 30 Dec 979).

• There is no proof that Bruno was the brother of Hermann Billung but this looks probable. It is assumed that Bruno's sons were adolescent or young adults when mentioned with their father in the two sources referred to below. This would place Bruno's birth in the range [905/15], which is too early for him to have been the son of Wichmann [II]. The reference to "pago Derlingum" in the [951/57] charter is a clear indication of a family connection as this territory appears several times in documents in which the supposed descendants of Wichmann [II] are named (see below). "Otto…rex" granted property "Hebesheim in pago Derlingum in comitatu Brunonis" to Moritzkirche, Magdeburg by undated charter, but dated to [951/57] as it names "coniugis nostræ Aelheidis…filii nostri Liudolfi", in the presence of "eiusdem Brunonis comitis filiique Liudolfi, Geronis marchionis, Cristiani comitis nec non Liutharii et Friderici comitum"[230]. "Otto…rex" gave property "in pago Hessi in comitatu comitis qui dicitur Bern in loco Uuestnetri" which "ibidem Bruninc comes filiusque eius Amalunc in beneficium habere visi sunt" to "fideli nostro Retolt" by charter dated 16 Nov 958[231]. "Otto…imperator augustus" gave judgment in a dispute between Werner Abbot of Fulda and Gozbert Abbot of Hersfeld, concerning ship travel along the Hörsel, by charter dated 30 Dec 979, which names "comites nostros Sigebertum, Sigefridum et Brunonem"[232], although if this refers to the same Count Bruno he would have been very old at the time.
• m ---. The name of Bruno's wife is not known.]
• Bruno & his wife had [two] children.

5. [son .

• The identity of the husband of Gerberga is unknown. The name of his son, Wichmann, suggests a close family relationship with the Billung family of dukes of Saxony. The connection appears confirmed by Widukind who records that Meinwerk Bishop of Paderborn was "materno a Wichmanno, Herimanni ducis nepote, propinquo Ottonis I"[236], the bishop's mother being corroborated in other sources as Adela, daughter of Wichmann [V]. There are so many uncertainties regarding the genealogy of the Billung family that detailed speculation on any precise relationship does not seem worthwhile. Gerberga's husband is shown as a possible son of Billung only for the purposes of making the hyperlink connection.
• m GERBERGA, daughter of MEGINHARD Graf van Hamaland & his wife ---. Her parentage is confirmed by the Necrologium of Elten which records the death of "Meginhard, pater Gerberch, cuius filius Wichmannus comes fundator ecclesia"[237].
• One child, Wichmann V, Graaf van Hamaland.

6. [---. m ---.]

• Had one daughter, who became wife to Richizo.

HERMANN [Billung] ([905/10]-Quedlinburg 27 Mar 973, bur Lüneburg St Michael).

• The Cronica Principum Saxonie names "Bilingus…filium Hermannum"[200]. His birth date range is estimated on the assumption that he was adult when appointed military commander in 936.
• He was given military command in Saxony ("princeps militiæ") by Otto I King of Germany in 936, which triggered the revolt of his brother Wichmann[201].
• Graf in Wetigau 940.
• Procurator of the king in Saxony 953, 961 and 966.
• "Otto…rex" granted property "Ozmina marcam…et Tarata marcam cum castello Grodista" to "vassallo Billing" by charter dated 26 Jun 952[202]. "Otto…rex" granted property to the church of St Moritz, Magdeburg by charter dated 953, which names "Billingus…noster miles"[203].

• Markgraf 956:
• "Otto…rex" granted rights to salt duties to Lüneburg St Mikhael at the request of "Herimanni marchionis" by charter dated 13 Aug 956[204]. "Otto…rex" gave property "in pago Usiti in comitatu comitis Willihelmi" to "nostro fideli vasallo comitique Billinc" by charter dated 2 Dec 958[205], which may refer to Hermann Billung although he is not titled Markgraf in the document. "Otto…rex" granted property "in locis Vurmerstat, Otunpach, Gozarstat, Haholtestat…in pago Usiti in comitatu comitis Uuillihelmi" to "vasallo comitisque…Billinc" by charter dated 2 Dec 958[206].

• He founded St Michaeliskloster at Lüneburg.
• The necrology of Fulda records the death in 973 of "Heriman dux"[209]. Thietmar records the death of Duke Hermann, father of Bernhard, at Quedlinburg on 1 Apr, the transportation of his body to Lüneburg, and the refusal by Bruno Bishop of Verden (maybe his nephew) to allow his burial in church because of his prior excommunication[210]. The necrology of Lüneburg records the death "27 Mar" of "Herimannus dux"[211].

The Genealogica Arnulfi Comitis names "Mathildis, filiam principis Herimanni" as wife of "Balduinum [filius comitis Arnulfi]", specifying that it was hoped that the couple would have many children[221]. This suggests that their marriage date may have been some years earlier than 961 considering that the Genealogia was supposedly compiled in [951/59], probably during the earlier part of this date range considering which children of Louis IV King of the West Franks are named in the document[222]. The Chronicle of Alberic de Trois-Fontaines names "Mathildis comitissa Saxonie" as wife of "Godefridi Ardennensis"[223]. "Heinricus…Romanorum imperator augustus" confirmed the rights and property of Kloster Mouzon donated by (among others) "dux Fredericus pro anima Ottonis…[et] Godefridus comes et coniux sua Mathildis pro anima sui fratris Adalberonis archiepiscopi" by charter dated 1023[224].

Her birth date range is estimated on the basis of her sister being born in [942] and Schwanehilde herself giving birth to seven children by her second husband.

From the Wikipedia entry on Hermann Billung:

http://en.wikipedia.org/wiki/Herman_Billung

http://de.wikipedia.org/wiki/Hermann_Billung

Hermann Billung (900 or 912 – 27 March 973) was a Margrave of Saxony and one of the most well-known members of the House of Billung.

Hermann was the son of Billung von Stubenskorn (c. 860-967) and Ermengarde of Nantes (b. 900). Hermann is generally counted as the first Billung Duke of Saxony, but his exact position is unclear. King Otto I appointed Hermann margrave in 936, granting him a march north of the Elbe between the Limes Saxoniae and Peene Rivers. Having more autonomy than his contemporary margrave Gero, Hermann exacted tribute from the Polabian Slavs inhabiting the March of the Billungs. He often fought against the West Slavic tribes of the Redarians, Abotrites, and Wagrians.

By 953 Otto I, who was also Duke of Saxony, began entrusting more and more of his authority in Saxony to Hermann during his absences. However, Hermann was never named as duke in royal documents. Instead, he is named as a military leader, count, and margrave. His son Bernard inherited and strengthened his father's position and managed to be recognized as duke.

(The German Wikipedia entry differs in defining the absences: in 953 was the Liudolfinischer Uprising, and in 961 was Otto's Second Expedition to Italy, saying that during both times Herman was appointed by King Otto as Procurator Regis, a position that gave him the full backing of the Saxon Court. Herman was also appointed Count in Wetigau, Tilithigau, Marsterngau, and Bardengau.)

Hermann had property around Lüneburg and founded the monastery of St. Michael in that city. He died in Quedlinburg.

[In the German Wikipedia entry, a more detailed history is given:

Fall 936, with the defeat of the insurgent Redarier, he is named Princeps Militiae and charged to limit any expansion by East Francia to the northeast along the Elbe River, and he was named Mark der Billunger.

953 - when Otto moved against his rebellious son Liudolf, he appointed Hermann as Procurator Register in Saxony, giving Hermann de facto powers as Duke, but not describing him as such (he was called Marchio and Comes). During this time, Hermann succeeded in driving out his nephew Wichmann II and Egbert the One-Eyed (both of whom sided with the rebels) from Saxony.

August 961 - Otto began his second expedition into Italy and finally made peace on 2 February 962 with Pope John XII in Rome, obtaining the title of Kaiser. During his absence, Hermann was appointed his deputy again in Saxony.

972 - Archbishop Adalbert of Magdeburg received Hermann like a king, sitting him at the King's place at his table and allowing him to take over his bed chambers. Otto I was angered by such presumption, and was removed from his deputy position.

Hermann was buried in the Klosters St. Michaelis in Luneburg, even though according to Dietmar of Merseburg he had been excommunicated by Bishop Bruno of Verden (and refused burial).]

[edit] Descendants

Hermann Billung was probably married twice, first to a woman named Oda (who died on 15 March in an unknown year, probably after 973), and second to Hildegarde (Hildesuith) of Westerbourg.

He had five children:

1. Bernhard I (c. 950 to 1011), Duke of Saxony (buried in the Church of the Monastery of St. Michael in Luneburg)

2. Liutger (died 26 February 1011) Count in Westfalengau (and Lesum), attested in 991, buried in St. Michaels in Lüneburg (Church of the Monastery of St. Michael), married Emma (of Lessum, 975/980 to 3 December 1038) who is buried in the Bremen Cathedral, daughter of Immed IV (Immedinger), sister of Bishop Meinwerk of Paderborn.

3. Mathilde (born between 935 and 945, died 25 May 1008 in Ghent St. Peter), married 1st in 961 to Balduin III, Count of Flanders (died 1 January 962), married second Gottfried der Gefangene (died on 3/4 April after 995) in 963/982, Count of Verdun (Wigeriche), buried in St. Peter's in Ghent

4. Suanhilde (born between 945 and 955, died 28 November 1014, buried in the monastery of Burg Kapellenburg south of Kleinjena (Jena), reburied after 1028 in the Georgskirche of Naumburg in Saale, married 1st in 970 Thietmar I (c. 920 to 3 August after 979) Margrave of Meissen, married (2) before 1000 Ekkehard I (murdered 30 April 1002 in Pöhlde); in 992 (or 987 according to the German Wikipedia) Margrave of Meissen, buried in the monastery of Burg Kapellenburg south of Kleinjena (Jena), reburied after 1028 in the Georgskirche of Naumburg in Saale.

Hermann av Sachsen (fødselsår ukjent, død i Quedlinburg i 973) av slekten Billung. I 936 ble han tildelt tittelen markgreve av Otto den store som takk for hans deltagelse i overvinnelsen av redarierne, obotrittene, wagrierne og danene. I 940 var han greve av Wetigau og i 953 utnevnte Otto ham til sin stedfortreder i Sachsen, noe som de facto gjorde ham til hertug uten at han hadde tittelen. Herman greide å fordrive nevøene sine, Wichmann II og Ekbert enøye, som sympatiserte med opprørerne fra Sachsen. I 955 opptrådte Hermann Billung som greve i Tilithigau og Marstengau, og i 956 ble han utnevnt til markgreve. Under Ottos reise til Italia i 956 og til Roma i 961 utnevnte han Herman på ny som sin stedfortreder i Sachsen.

Herman var gift med Oda og senere med Hildeshuith, og med dem hadde han barna:

Bernhard I av Sachsen (-1011)

Ludger (-1011)

Suanehilde (-1014), gift med markgreve Thietmar I av Meißen (-979) og deretter med markgreve Ekhard I av Meißen (-1002)

Imma, abbedisse i Herford

Mathildis (942-1008), gift med greve Boudewijn III av Flandern (940-962) i 961 og i 963 med grev Gottfried av Verdun (930-1002).

Forgjenger:

Otto II  Hertug av Sachsen

(961–973) Etterfølger:

Bernhard I av Sachsen  

--------------------

General Notes:

Han var stamfar til det Billungske hus. Forbindelsen med den eldre Billungslekten er usikker. Det er mulig at hans far var Billung som var greve av Sachsen og som døde i 967.

Hermann døde i 973 antagelig ca. 70 år gammel.

Billungslekten etterfulgte Liudolfingerslekten som hertuger av Sachsen fra 961 til 1106 og ble etterfulgt av Askanierslekten. Hertugdømmet Sachsen var en del av det tysk-romerske riket.

Research Notes:

Burke says he was Conrad I, le Pacifique, Roi de Bourgogne Transjurane.

Noted events in his life were:

• Acceded: Duke of Saxony, 961.

Unattributed and with errant information (no such thing as "Stubenskorn" - don't agree? Try identifying it on a map...):

Hermann was the son of Billung von Stubenskorn (c. 860-967) and Ermengarde of Nantes (b. 900). Hermann is generally counted as the first Billung Duke of Saxony, but his exact position is unclear. King Otto I appointed Hermann margrave in 936, granting him a march north of the Elbe between the Limes Saxoniae and Peene Rivers. Having more autonomy than his contemporary margrave Gero, Hermann exacted tribute from the Polabian Slavs inhabiting the March of the Billungs. He often fought against the West Slavic tribes of the Redarians, Abotrites, and Wagrians.

By 953 Otto I, who was also Duke of Saxony, began entrusting more and more of his authority in Saxony to Hermann during his absences. However, Hermann was never named as duke in royal documents. Instead, he is named as a military leader, count, and margrave. His son Bernard inherited and strengthened his father's position and managed to be recognized as duke.

Hermann had property around Lüneburg and founded the monastery of St. Michael in that city. He died in Quedlinburg.
