m (1009) HEDWIG, daughter of --- (-after 1034). The Annales Scafhusenses record the marriage in 1009 of "Ebbo comes de Nellenburc" and "consobrinam Heinrici regis Hedewigam…de curie regis"[638]. If "consobrinam" is here used in its precise sense, Hedwig would have been the daughter of one of the sisters of Gisela, daughter of Conrad I King of Upper Burgundy. According to the early 12th century Vita Eberhardi[639], the mother of Eberhard Graf von Nellenburg (son of Eberhard [IV] Graf im Zürichgau) was --- of Hungary, daughter of István I King of Hungary, although it is somewhat surprising that such a prominent figure as King István, in far off Hungary, would have married his daughter to an obscure Swiss count. If Hedwig was the daughter of King István, there is a remote possibility that she was the same daughter who supposedly married Edmund ætheling, although if this is correct she would have been much older than her second husband. This supposed Hungarian origin appears unlikely, given Hedwig’s property holding in Rheingau mentioned in the following document: “comes Eberhardus cum domina Hadewiga matre sua” founded Kloster Pfaffen-Schwabenheim bei Kreuznach with his mother’s property “im Rheingau” by charter dated 1034[640]. https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
Graf Eberhard [IV] & his wife had [four] children:

1. BURKHARD [II] (-killed in battle Civitate 18 Jun 1053, bur Reichenau). "Eberhardus comes filius Eberhardi quondam comitis" donated property to Reichenau, for the souls of "patris mei Eberhardi et fratrum meorum Purghardi et Manegoldi" by charter dated 1056[641]. https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
2. MANEGOLD (-killed in battle Falkenstein, Schwarzwald 17 Aug 1030, bur Reichenau). The Annales Sangallenses name "Manegolt comes" in 1030[642]. "Eberhardus comes filius Eberhardi quondam comitis" donated property to Reichenau, for the souls of "patris mei Eberhardi et fratrum meorum Purghardi et Manegoldi" by charter dated 1056[643]. https://fmg.ac/Projects/MedLands/SWABIAN%20NOBILITY.htm#_Toc514513192
3. EBERHARD(-26 Mar [1076/79]). According to Europäische Stammtafeln, Eberhard was the son of Graf Eberhard [IV], built the castle of Nellenburg before 1050 and was ancestor of the Grafen von Nellenburg[644]. Graf im Zürichgau. “Comes Eberhardus cum domina Hadewiga matre sua” founded Kloster Pfaffen-Schwabenheim bei Kreuznach with his mother’s property “im Rheingau” by charter dated 1034[645]. "Eberhardus comes Turegie provincie" exchanged property with "Bertholdo Carinthiorum duce" by charter dated early Mar 1050, witnessed by "…Burchardus et Eberhardus et Adelbertus, filii Eberhardi comitis…"[646]. This charter is presumably misdated as Berthold did not become Duke of Carinthia until 1061, and his son Marchese in 1072. The Annales Scafhusenses record that "Eberhardus comes de Nellinburc" founded "Scafhusensem locum" in 1052[647]. "Eberhardus comes filius Eberhardi quondam comitis" donated property to Reichenau, for the souls of "patris mei Eberhardi et fratrum meorum Purghardi et Manegoldi" by charter dated 1056[648]. "Heinricus…rex" granted property "in villa Kiricheim in pago Nechargovve in comitatu Eberhardi comitis" to "prefatus Eberhardus comes" by charter dated 22 Nov 1059[649]. "Heinricus…rex" granted property "duas villas Hochfeld et Suueichusen cum foresto Heiligenforst in comitatu Gerhardi comitis in pago Nortcowe" to "Eberhardo comiti" by charter dated 22 May 1065[650].

The Historia Trevirensis names “ex Alamannorum prosapia oriundus patre Eberhardo comite, matre Ida” as parents of “Udo” Archibishop of Trier, adding that they founded “monasterii…Scafuse”[652]. She became a nuun at St Agnes, Schaffhausen as shown by the charter dated 1 Mar 1080 under which her son "Comes Burchardus de castello Nellenburk" confirmed donations to "monasterium sancti Salvatoris in pago Cletgouve in villa Schafhusa super litus Reni" founded by "progenitoribus meis…Eberhardo, ex religioso comite in eodem monasterio monacho…facto, et Ita…monachicam…in cella sancte Agne in eadem villa"[653].

►Note from Farkas Mihály László: According http://thepeerage.com/p10667.htm#i106661 Eberhard was the 1st husband of Hedwig, the second one was Edmund (?), son of Edmund II 'Ironside', King of England and Ealdgyth (?). He was born ~1016/17. Eberhard born ~980/90. Hedwig parents were married 995/996. It is almost impossible that the both named person were Hedwig's husbands. If even existed Gizella, she was perhaps Edmund's wife.

https://www.genealogieonline.nl/en/genealogie-richard-remme/I65848.php Citing Kurt Hils, it lists these children using Google translate: Manegold II, Eberhard I the Blessed, and Burkhard II.

The same site gives a date of birth of 980-990 and date of death 1030-1034 based on GENEALOGICAL MANUAL OF SWISS HISTORY Volume IV

The same site cites Hils, Kurt: The counts of Nellenburg in the 11th century. Your position on the nobility, the empire and the church, Eberhard Albert Verlag Freiburg 1967, pages 13,18-23,25,30,39,46-49,54,58,68,75 - From that section comes this, "According to the entry in the Einsiedler Nekrolog, Eppo would have died in February. The donor book places the death of Eppos in the youth of his son Eberhard; this source also reports that after Eppos' death, his wife Hedwig withdrew to her own property in Nahegau and there with her son Eberhard founded a monastery in Pfaffenschwabenheim (Bingen district). We would like to relocate Eppos' death to the years 1030-1035, although a few years do not matter. This also fits in with the fact that the Laurentius Chapel on Reichenau, in which Eppo is buried, was consecrated under Bishop Eberhard von Konstanz (1034-1049). Why Eppo is said to have been born as early as 970, that is, why he would not have married until about 39 years old (about 1009, Eppo married), is incomprehensible to us; To assume an earlier marriage before 1009 is a pure construction of genealogists. ."

The same site cites Hans Kläui: page 187 which mentions his son Eberhard the Blessed and states Eberhard V died before the time of the Constance Bishop Eberhard (1034-1046).

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

Excerpted from https://de.wikipedia.org/wiki/Nellenburg :

Nellenburg is an early medieval castle ruin west of Stockach in the district of Konstanz in Baden-Württemberg in Germany.

• Alternative name (s): Castellum Nellenburc
• Creation time : around 950
• Castle type : Höhenburg, spur location
• Conservation status: ruin
• Standing position : Count
• Place: Stockach
• Geographical location 47 ° 50 ′ 55 " N , 8 ° 59 ′ 5" E
• Height: 613 m above sea level NHN
• Nellenburg (Baden-Wuerttemberg)

It formed the center of power in the Landgraviate of Nellenburg.

The ruins of the former Spornburg (613 m above sea level) are located around two kilometers west of the old town of Stockach on a molasses spur, not far from the Nellenburger Berg (624 m above sea level). This is Stockach's local mountain, which was strategically located at the western end of Lake Constance in the Middle Ages and today borders a nature reserve.

Almost 300 meters east of the castle ruins is the “young Nellenburg” with the “Nellenburg” mountain inn, but also in an exposed location. The "four-country panorama" results from a very clear view, with a view of Lake Constance and Hegau, the Austrian, Swiss, and even the French Alps.

Nellenburg had been the seat of the Counts of Nellenburg since the middle of the 10th century and was first mentioned in 1056 as "castellum meum Eberhardi comitis Nellenburc". However, in 958 a Godfridus de Nellenburg is attested--that is, the castle already existed in the 10th century. The time it was founded is still unknown, as is its building history.

The owner, Eberhard Graf von Nellenburg (* 1010 at Nellenburg Castle, † January 25, 1078 in Schaffhausen), a relative of the Emperors Konrad II and Heinrich III, founded the Benedictine monastery of All Saints in Schaffhausen in 1049, in which the monitoring of the "lower landscape" Landgraviate of Nellenburg was based on the three castles on the Hohenstoffeln, the Hohenstoffeln ruins.

Around 1050, the Nellenburgers moved the main focus of power from Zürichgau to the Upper Rhine in order to protect their newly created centers, the Allerheiligen Monastery in Schaffhausen and Nellenburg Castle.

As a result of the investiture controversy, Count Burkard († 1105), the last of the older line of Nellenburg, lost the castle, which passed to his nephew Count Dietrich in 1105; parts of the land went to Count Adalbert von Mörsberg. The von Bürgeln form the so-called middle line of Nellenburg.

In 1170, the County of Nellenburg was married to the Counts of Veringen, who, after dividing an inheritance from 1216 to 1422, founded the younger line of Nellenburg.

In 1291 Duke Albrecht of Austria besieged Nellenburg, at that time the seat of Count Mangold II of Nellenburg (-Veringen), who had taken part in the uprising of Swabian nobles against Habsburg. The round main tower collapsed at that time due to undermining.

In 1422 Nellenburg also passed into the possession of its heirs, the Lords of Tengen, who from then on became known as Counts of Tengen. They sold the Landgraviate of Nellenburg in 1465 for 37,905 guilders to Archduke Sigismund of Austria (Habsburg).

Stockach was the main town of the Landgraviate of Nellenburg until the middle of the 15th century and then passed into Habsburg ownership. For 340 years, from 1465 to 1805, Stockach and the county of Nellenburg belonged to Upper Austria.
