Immediately before the Conquest, Blyford was held by Edwin the Thegn, whose will includes a bequest of land to Blyford church (Whitelock). The manor was held by Godric the Steward in demesne in 1086. The holding then included a church with 12 acres. By 1203 the manor had passed to the family of de Criketot, lords of Munchensy, and by 1280 to the Bavents by marriage. The church was granted to Blythborough priory by Ralph de Criketotc.1199, and remained a possession of the priory until the Dissolution.
