BERTHOLD, son of --- (-15 Jan 980). m ([970]%29 EILIKA [Eiliswintha or Eila] von Walbeck, daughter of LOTHAR [II] Graf von Walbeck [Nordmark] & his wife Mathilde von Arneburg (-19 Aug 1015). Markgraf Berthold & his wife had [three] children:

1. HEINRICH von Schweinfurt ([970/75]-18 Sep 1017, bur Schweinfurt). His parentage is specified in the Annalista Saxo[1088]. His birth date range is based on his parents' estimated marriage date. Graf an der unteren Naab 981. Graf an der unteren Altmühl 983. Markgraf auf dem bayerischen Nordgau 994. Graf im Radenzgau 1002. He rebelled against Heinrich II King of Germany in 1003 on the grounds that he had not been granted the duchy of Bavaria as promised and allied himself with Bohemia and Poland. His rebellion was crushed and King Heinrich set up the bishopric of Bamberg to provide central control in the area in place of the margravate of bayerischen Nordgau[1089]. Graf an der Pegnitz 1009 and 1011. Graf an der oberen Naab 1015. Thietmar records the death 18 Sep 1017 of "Markgraf Heinrich my aunt's son and the glory of eastern Franconia"[1090]. m (before 1003) GERBERGA [von Hammerstein], daughter of HERIBERT Pfalzgraf Graf im Kinziggau & his wife Imiza--- ([975/80]-after 1036). Thietmar names "Ottone germano sui", referring to Gerberga wife of Heinrich von Schweinfurt, whose captivity is recorded in the preceding paragraph, an earlier paragraph referring to "Heriberti comitis filio Ottone" which appears to refer to the same Otto[1091]. An alternative possibility is that Gerberga was the daughter of Otto Graf von Grabfeld, the solution chosen by Europäische Stammtafeln[1092], but this assumes that the two references to "Otto" in Thietmar were to different individuals. It is also less likely chronologically as it would appear that Otto Graf von Grabfeld was several decades older than Otto Graf von Hammerstein. Her birth date range is estimated on the basis of her daughter Eilika having given birth to her first child in [1020]. Thietmar states that Gerberga and her children were guarded by her husband's brother Bukko during their rebellion against Heinrich II King of Germany in 1003[1093]. Markgraf Heinrich & his wife had [five] children:

a) OTTO von Schweinfurt (-28 Sep 1057, bur Schweinfurt). Graf an der unteren Altmühl 1014. Markgraf auf dem Nordgau 1024-1031. Graf an der unteren Naab 1034. Graf an der oberen Naab 1040. He succeeded in 1048 as OTTO Duke of Swabia.
b) EILIKA ([1000/05]-10 Dec after [1055/56]). m ([1020]%29 BERNHARD II Duke in Saxony, son of BERNHARD I Duke in Saxony [Billung] & his wife Hildegard von Stade (after 990-29 Jun 1059, bur Lüneburg St Michael).
c) JUDITH (-2 Aug 1058, bur [1061 or after] Prague St Veit). m [firstly] (after 1021) BŘETISLAW of Bohemia, illegitimate son of OLDRICH Duke of the Bohemians & his mistress --- (-Chrudim 10 Jan 1055, bur Prague St Veit). He succeeded in 1034 as BŘETISLAW I Duke of Bohemia. [m secondly ([1055]%29 as his second wife, PÉTER Orseolo King of Hungary, son of PIETRO OTTONE Orseolo Doge of Venice & his wife Maria [Grimelda] of Hungary ([Venice] [1010/15]- Székesfehérvár late 1046
d) BURKHARD (-18 Oct 1059). Chancellor of Emperor Konrad II. Bishop of Halberstadt 1036.]
e) HEINRICH (-after 1043).

Heinrich von Schweinfurt

Heinrich von Schweinfurt (* vor 980; † 18. September 1017) war Markgraf von Schweinfurt.

Herkunft

Heinrich, auch genannt Hezilo, war der Sohn des Markgrafen Berthold, Graf des östlichen Frankens, und der Eilika, eine geborene von Walbeck und Gründerin des Benediktinerklosters Schweinfurt. Er wurde 981 Graf an der unteren Naab, 983 Graf an der unteren Altmühl, 994 Markgraf auf dem bayerischen Nordgau und 1002 Graf im Radenzgau.

Familie und Nachkommen des Heinrich

• Er heiratete vor 1009 Gerberga († nach 1036), Tochter des Otto von Henneberg (Graf im Grabfeld) oder des Grafen Heribert im Kinziggau (Konradiner). Mit ihr hatte er mindestens drei Kinder:

1. Otto von Schweinfurt, † 28. September 1057, ab 1048 Herzog von Schwaben; ∞ 1036 Irmingard, † 1078 vor 29. April, Tochter des Markgrafen Ulrich Manfred von Turin und Berta degli Obertenghi, die in zweiter Ehe 1058 Graf Ekbert I. von Braunschweig, Markgraf von Meißen († 11. Januar 1068) (Brunonen) heiratete Eilika, † 10. Dezember nach 1055-1056, ∞ Bernhard II. Herzog in Sachsen, † 29. Juni 1059 (Billunger)
2. Judith, † 2. August 1058; ∞ I nach 1021 Břetislav I. Herzog von Böhmen, † 10. Januar 1055 (Przemysliden); ∞ II April 1055 Peter König von Ungarn, † 30. August 1059 (Arpaden)
3. Burchard, Bischof von Halberstadt
4. Vermutlich hatte er einen weiteren Sohn, Heinrich, der 1021-1043 als Graf an der Pegnitz und 1043 als Graf an der oberen Naab bezeugt ist, und von dem wiederum angenommen wird, dass er der Stammvater der Grafen von Lechsgemünd, Horburg und Graisbach ist.
