Guigues I of Albon

The official history written by George de Manteyer has caused him to be known as the first Dauphin of Viennois, despite this designation only appearing a century later.

Thereafter, he was a landowner in Champsaur (1027), in Oisans with the title of count (1035), Grésivaudan (around 1050), Briançonnais (around 1053), and in the valley of Oulx (1070).

It is not known how Guigues took possession of the lands, but his power enabled him to install family members as bishop.

His brother was bishop of Valence and the archbishop's palace at Vienne, attached to the most prestigious church of the province, was in the hands of a cousin by marriage.

He married Adelaide, who seems to be of the family of the counts de Turin, and had a son, Guigues II (1025–1079), who succeeded him.
