He is married to Aramburge Nn.
They got married
Child(ren):
DALMAS [I] de Semur, son of GEOFFROY [I] Seigneur de Semur & his first wife --- de Brioude (-murdered 1048). The genealogy of the Seigneurs de Semur, included in the cartulary of Marcigny-sur-Loire and dated to [1144], names "Dalmace" as son of "Jaufrois qui eut la fille de Dalmas Vicomte de Briode"[287]. His paternity is deduced from the charter of "Gaufredus" dated [1054] which names "patris mei Dalmatii [et] avi Gausfredi" as well as "Tetbaldus comes avunculus ipsorum" (referring to Geoffroy and Dalmas, sons of this Dalmas)[288]. He succeeded his father in [1020] as Seigneur de Semur. The Vita S Hugonis records that "Dux Burgundie, gener eius" killed the father of St Hugues (abbot of Cluny) by his own hand[289].
m ARAMBURGE, daughter of ---. The genealogy of the Seigneurs de Semur, included in the cartulary of Marcigny-sur-Loire and dated to [1144], names "Aremburge qui fut sœur du comte Tetbauld" as wife of "Dalmace"[290]. It is uncertain to whom this refers, but if it is Thibaut Comte de Chalon the entry is an error as he was her husband's brother. A manuscript now lost records "Aremburgis de Vergy" as wife of "Dalmatii…de Sinemuro"[291]. "Gaufredus" donated property to the abbey of Marcigny-sur-Loire for souls of "genitoris mei Dalmatii et genitricis meæ Aremburgis" by charter dated to [1055/80] which refers to "Cluniacensis monasterii ubi domnus Hugo frater meus præest"[292].
Dalmas [I] & his wife had nine children:
HELIE ([1016]-Semur-en-Brionnais, Saône-et-Loire 22 Apr after 1055).
