Baldwin de Vernon de Reviers

From wikipedia:

The Domesday Book of 1086 records the village as Haiford, with a manor or 10 hides that was one of the many estates of the Norman baron Robert D'Oyly.[2] Along with many manors of the D'Oyly estate, Heyford became part of the Honour of Wallingford.[2] The manor was tenanted by the de Chesney family until the late 12th century, when Maud de Chesney became married to Henry FitzGerold, chamberlain to Henry II.[2] Maud left the manor to her eldest son Warin, who had succeeded to the manor by 1198 and after whom the village became called Heyford Warren.[2] Warin's daughter Margaret married Baldwin de Redvers, son of William de Redvers, 5th Earl of Devon.[2] Heyford Warren remained with the Earls of Devon and thereby passed to Isabella de Fortibus, Countess of Devon in 1262.[2]
