Ivo Taillebois was a Norman most probably from
Taillebois, now a small hamlet in Saint-Gervais de Briouze,
Calvados. He sold land at Villers to the
Abbey of Saint-Étienne, Caen and donated a church of Christot in Calvados. Hereward escaped capture during the siege but was caught and imprisoned; Taillebois dissuaded William from freeing him. His
power base appears to have been in Lincolnshire, where he probably became
High Sheriff of Lincolnshire before 1068. He married
Lucy, daughter of Turold, the Sheriff of Lincolnshire before the conquest, later
Countess of Chester, in whose name he held the extensive honor of Bolingbroke in Lincolnshire. In the Domesday Book of 1086 he appears as a tenant-in-chief also holding
Bourne and many of its manors. Ivo attested several charters for William the Conqueror before 1086, including the
abbey of St. Armand and the abbey of St. Peter, Ghent, and several for William II Rufus including the
abbey of St. Florent,
Saumur and the
abbey of St. Mary, La Sauve Majeure. ==Family==
