GEBHARD (-killed in battle near Augsburg [22] Jun 910). m ---. Duke Gebhard & his wife had two children:

a) UDO ([895/900]-949). m ([915]%29 [CUNIGUNDIS] de Vermandois, daughter of HERIBERT [I] Comte de Vermandois & his wife [Lietgardis] --- ([890/900][302]-after 943). Udo & his wife had three children:

i) GEBHARD ([918/20]-killed in battle 938).
ii) OTTO ([920/25]-).The notice concerning the Hammerstein marriage dispute names (in its first part) "Gebehard et Udo nepotes, filii duorum fratrum. Gebehard genuit Cunonem. Udo genuit Ottonem. Cuno genuit Cunonem. Heribertus genuit Ottonem"[306]. It is not impossible that Otto was the same person as Udo's son Udo, although this text suggests that the two names were from different roots.
iii) UDO (-26 Aug 965). Regino records the election as Bishop of Strasbourg in 950 of "Udo filius Udonis comitis"[307]. He was elected Bishop of Strasbourg 13 Aug 950.

b) HERMANN (-10 Dec 949, bur Reichenau Island).
