A manuscript genealogy of the founders of Horsham priory, Norfolk records that “domina Sibilla, soror Johannis de Cayneto, filia Radulfi de Cayneto qui venit ad conquestum Angliæ” married “domino Roberto filio Walteri fundatori domus sanctæ Fidis de Horsham”. “Robertus Walteri filius et uxor mea...Sibilla” founded Horsham priory, with the consent of “Rogero et cæteris filiis meis”, by undated charter which lists the priory’s properties. 1
