Olivier of Dinham, having received some of his cousin Roland’s possessions which escheated during 1169 (for which see below, p. 176), between 1189 and 1199 concluded an agreement with his nephew, Olivier III de Dinan (himself the son of Geoffrey II, and thus lord of Dinan nord), which separated the lands of Olivier III’s father Geoffrey II into ‘all lands… which my father held in Brittany’ to be retained by the son (and nephew) Olivier III, and ‘all lands… which my father held in England’ to be held by the cousin (and uncle) Olivier of Dinham. This agreement… must have significantly contributed to the establishment of the family of Olivier of Dinham as an English (and specifically west-country) family. The family of the second son of the Breton Olivier II de Dinan, Olivier of Dinham, was well-entrenched among the Cornish and Devonshire gentry to 1501.
"It seems at least possible that the ‘English’ family of Olivier of Dinham kept some of their Breton rights… Certainly, at least for practical reasons, the involvement of the British Dinham family with the French priory of Marmoutier concerning the manors of Harpford and Nutwell (themselves used to support the priory of Saint-Malo at Dinan) extended well into the thirteenth century. [NOTE 98: In 1268 Oliver of Dinham (the great-great-grandson of the first Olivier of Dinham) purchased the interest in Harpford and Nutwell from Marmoutier.]

Different sources give Oliver III of Dinan two possible mothers or two different names for his mother if Agnorie and Gunnor are one and the same person. If they are separate people Oliver's mother is presumed to be Agnorie.
