Jean (John, Johannes) de La Flèche is first known from a charter of 1032×1052, when Agnès, wife of count Geoffroy Martel, purchased the church of Saint-Bienheuré de Vendôme from Jean's father Lancelin de Baugency, and acquired the church of Saint-Jean de Châteaudun from Jean and his brother Lancelin ["a Lancelino dominico vasso de castro Balgentiaco, ...; ... a filiis ejusdem Lancelini, scilicet Johanne et Lancelino, ..." Cart. Trinité de Vendôme, 1: 43 (#22)]. He was evidently lord of La Flèche by 1081, based on his appearance in a charter of 1060×1081: ["Johannes de Feza" Cart. S.-Aubin 1: 297 (#254)]. Jean de La Flèche was still living on 13 February 1087, when he made a donation to Saint-Aubin.
