Fulk I was associated with the Peverels: William Peverel the Younger granted him a knight's fee in Tadlow, Cambridgeshire, before 1148 which King Henry II confirmed in 1154. Henry rewarded Fulk I for his support of the Empress Matilda during the civil war by conferring upon him the royal manor of Alveston in Gloucestershire (by 1155) and the manor of Whadborough in Loddington, Leicestershire. His son Fulk II held those properties after the death of his father in 1171. In the time of Robert Foliot, Bishop of Hereford (1174-1186), Fulk II gave land at Tadlow to Shrewsbury Abbey to settle a controversy over the patronage of the church of Alberbury, Shropshire, in his own favour. The FitzWarin land tenure at Alberbury, held from the Fee of Caus, was therefore presumably already in place.
