Henry de Sibitun, who, having forfeited his Bosc in 1231, was obliged to fine one merk to recover it out of the King's hand. The Feodary of 1240 sets down Henry de Sibbeton as holding one knight's-fee in Sibbeton, of the Barony of Clun. His attestation of a grant to Haughmond Abbey is some years later. In January 1250, the Justice of the Forest set various arrentations on persons resident in the vicinity of Sibton. Richard de Sibeton and Richard Provost were jointly assessed 9d. for half an acre and one perch of Tillage: Philip de Sibeton and Martin fitz Martin were each assessed 9d. for an acre in Wynestanes; and William de Hordesleg was assessed 4½d. for half an acre in the same locality....
In 1255 it appears that Henry de Sibton was deceased, leaving a son under age. It would also seem probable that Roger Bardulf, guardian of the son, had married the father's widow, and so obtained temporary possession of the whole Manor. 1
