(d. 1314). Geneville, the brother of Jean, Sire de Joinville, the biographer of St Louis, spent a long life in English royal service. He accompanied the future Edward I on crusade in 1270, fought in Wales, and went on diplomatic missions. But much of his career lay in Ireland. One of the Savoyard group at Henry III's court, by 1252 he had married Matilda, grand-daughter of Walter de Lacy, who brought him a half-share of Meath and the Lacy lands in Britain. He was acting justiciar 1264–6, when he pacified baronial feuds, and justiciar 1273–6, when he had little success against the Leinster Irish. He assiduously defended his liberty rights in Trim, and defined his tenants' military duties. In 1308, when he was about 80, he resigned his lordship to Roger Mortimer, the husband of his granddaughter, retiring to the Dominican priory at Trim, where he was buried.
