"Ancestral Roots..." (Balt., 1992) 214-24: "Stephen I, Count of Brittany, held the honour of Richmond in England, founder
of the Augustinian abbey of Ste. Croix at Guincamp ca. 1110, founder of Cistercian abbey of Begard, d. 21 Apr. 1135 or
1136, bur. in the choir of St. Mary's, York; m. Hawise (said to have been the Countess of Guincamp, which is doubtful)."
226-24 gives half-brother of Stephen: "Bardolf (nat. son of Eudes), ancestor of the Lords Fitz Hugh of Havensworth;
brother of Bodin who held Ravensworth, Mickleton, Romandkirk, etc., in Domesday Book 1086."
