He is named as son of King Henry by Orderic Vitalis[119]. The Chronicle of Gervase names "fratre suo Reginaldo comite Cornubiæ" as one of the main supporters of Matilda[120]. The Complete Peerage deduces his mother´s identity from the charter under which "Reginaldus, Henrici Regis filius, comes Cornubiæ" granted property to "Willielmo de Boterell, filio Aliziæ Corbet, materteræ meæ" which he had granted to "Willielmo de Boterells in Cornubia, patri…predicti Willielmi" on his marriage, witnessed by "Nicholao filio meo…Herberto filio Herberti, Baldwino et Ricardo nepotibus meis, Willelmo de Vernun, Willielmo fratre meo…Hugone de Dunstanvill…"[121]. His birth date range is estimated on the basis of his marriage in [1141]. According to Domesday Descendants[122], "de Dunstanville" was a label only attributed to him by Orderic Vitalis. He inherited large areas of land in Cornwall, by right of his wife, on his marriage and was created Earl of Cornwall in [Apr 1141] by his half-sister Empress Matilda, after successfully leading a rebellion in her favour in the West Country[123]. The title was later fully recognised by King Stephen. Earl Renaud was a witness to the treaty between King Stephen and Henry Plantagenet in 1153[124]. Sheriff of Devon 1173-1175. "Reginaldus, Henrici Regis filius, comes Cornubiæ" granted property to "Willielmo de Boterell, filio Aliziæ Corbet, materteræ meæ" which he had granted to "Willielmo de Boterells in Cornubia, patri…predicti Willielmi" on his marriage, by charter dated to [1163/75], witnessed by "Nicholao filio meo…Herberto filio Herberti, Baldwino et Ricardo nepotibus meis, Willelmo de Vernun, Willielmo fratre meo…Hugone de Dunstanvill…"[125]. The Chronicle of Gervase records the death "mense Decembrio 1175" of "Reginaldus comes Cornubiæ regi Henrici secundi avunculus" and his burial at Reading[126].
