A manuscript which records the foundation of Kirkstead abbey, Lincolnshire states that "Robertum filium Hugonis" was succeeded by "Johannes filius eiusdem Roberti et hres" who had "fratrum Robertum etfilium et hredum Walterum".It should be noted that a mid-15th century source records that three of the sons of Ribald, whose wife may have been the daughter of Ivo Taillebois as shown above, were named Taillebois.The accuracy of such a late source to record events which occurred more than 300 years earlier is uncertain, but the document does demonstrate the possibility that the name Taillebois was transmitted outside Ivos direct family.

Domesday Book records that Peter de Valognes and Ralph Taillebois took Welbury in Hertfordshire from "Ilbert [who] put it in his manor of Lilley while he was sheriff", daughter of ---.
