Simon de Joinville, hereditary Seneschal of Champagne, defended Troyes in 1230 against the enemies of Count Thibaut IV.

Geoffrey de Joinville (d. 1314), 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.
