Note 10 — Chapter XXII

GILBERT CRESPIN was then lord of TILLIERES, arrondissement of Evreux. The building of the castle is described by Wace, i. 335. He is considered to have been a younger son of Gilbert I. mentioned before by Wace, vol. ii. 3. 5; and must not be confounded with Gilbert earl of Brionne, guardian to the duke. In the Red book, 'Gilbertus de Teuleriis 3 mil. et ad servitium suum 4 mil.' With reference to this family, (embracing Turstin Fitz-Rou above mentioned, and William Crespin, who will soon occur) Mr. Grimaldi has given in the Gentleman's Mag. Jan. 1832, some curious materials; bearing also on the probable origin of the Mareschals. His pedigree is as follows:

This pedigree differs, it will be seen, from the usually received accounts, and in some respects from the genealogy in the appendix to Lanfranci opera by D'Achery. Whether the latter is entitled to more weight than most of these monastic genealogies we do not pretend to decide. According to that authority, however, William Crespin had a sister Hesilia, who was mother of William Malet, who, it states, died an old man at Bec. She would thus appear to be the wife of Turstin Fitz-Rou, the grandfather of Vauquelin Malet.
