He was granted the honour of Château-du-Loir by Geoffroy "le Barbu". The canons of Saint-Pierre-de-la-Cour relinquished vines to Abelin by charter dated [1051/62] naming "Herberto, Cinomannorum comite, cum fidelibus suis, Rotberto filio Hamelini". The absence of Robert from the list of those consenting to the donation of his son Gervais dated [Sep 1067/23 Sep 1068]... implies that he had predeceased the donation. On the other hand, his son Gervais is named "Gervasium filium Roberti" in a charter dated 8 Mar 1071, which suggests that his father might then still have been alive.
The necrology of Le Mans Cathedral records the death "II Kal Jul" of "Robertus filius Haimonis de Castrolidi". 1
