Before DS the manor of Weston was held by Alestan de Boscumbe, a thegn of Edward the
Confessor. At the time of DS it was held by William de Ow. Henry I later granted the
manor to Walter, son of Richard de Clare after the forfeiture of William de Ow. In
King Stephen's reign they were held by Gilbert de Clare, Earl of Pembroke. After
Gilbert's death in 1148 his son, Richard Strongbow inherited the manor. After
Richard's death in 1176, his widow Eva who was daughter of Dermot, King of Leinster,
continued to hold the manor, and it descended via her daughter Isabel.
The advowson of the church was awarded by Gilbert de Clare to the Knights Templar
prior to 1148. This was later confirmed by William Marshall, Earl of Pembroke, the
husband of Isabel. The Templars held the advowson until 1309, when their order was
suppressed, and it then passed to the Knights Hospitallers.
