A manuscript genealogy of the founders of Horsham priory, Norfolk names “tres filias...Margaretam, Clementiam et Saram” as the children of “Willielmum de Caineto”, son of “domino Roberto filio Walteri fundatori domus sanctæ Fidis de Horsham”, adding that “Margareta” married firstly “cuidam Normanno Hugoni de Crescy”, by whom she had “filium...Rogerum” who married “Isabellam de Ry” and had “quatuor filios...Hugonem, Rogerum, Johannem et Stephanum” all of whom died childless, and secondly “Roberto filio Rogeri”.
The Testa de Nevill includes a list of landholdings in the honour of Boulogne, dated to [1217/18], which includes "uxor que fuit Roberti filii Rogeri" holding "vii milites…in Torpwidon et Andeg et Massingham et Anemere et Freinges et Wikinham vi milites quos Hugo filius Roberti tenet". The Pipe Roll 1223 records “Margarete que fuit uxor Robert f Rogeri...in Blieburg” in Norfolk/Suffolk. 1
