"Domna comitissa Adheleidis [Teudbaldi comitis filia]" donated property to Paray-le-Monial with the consent of "domnus Wido de Tier filius eius, domnus Hugo Dalmatius, domnus Gaufredus Donzi" by undated charter.

He succeeded [his maternal uncle in 1078] as Comte de Chalon, but shared the county with Geoffroy de Donzy. An undated charter records that "Gaufridus de Dunziaco" held "partem mediam comitatus Cabilonensis" together "cum Wydone de Tyhæra".
