Kinship and identity in eleventh-century Normandy: the case of Hugh de Grandmesnil, c. 1040-1098

Hugh de Grandmesnil was one of the co-founders of the Norman monastery of Saint-Evroult. It was no doubt his part in this foundation that led Orderic Vitalis, a monk of that house, to provide an account of Hugh's career in his Historia ecclesiastica. The information found there provides an almost unique opportunity to observe an individual of the eleventh century in the context of nearly all of his family connections. This article uses that evidence first to examine Hugh's relationships with his kinsmen and to ask whether they acted together so as to form, in Sir James Holt's words, a 'mutual benefit society', and secondly to consider the extent to which Hugh's identity was defined by his relations with his kinsmen. The findings of this inquiry reveal, amongst other things, that the importance of Hugh's relationships with his kinsmen varied over the course of Hugh's career, and that the pool of kinsmen, friends, and allies to whom Hugh could turn in time of need was equally fluid. Hugh's career therefore stands as a corrective to frequently held assumptions that the relationships forged by kinship and marriage between members of the secular elite of eleventh-century Normandy remained stable throughout an individual's life.
