He [Walter de Coleville] married Isabel or Elizabeth (e). Hedied 1277, before 2 September, when the writ for his Ing. p. m.is dated. [Complete Peerage III:374, (transcribed by DaveUtzinger)]
(e) Aubourn, Counthorpe, and other of his manors, co. Lincoln,were committed, 25 Oct 1265, to Isabel late (sic) the wife ofWalter de Coleville; where also, 20 Feb 1265/6, is a grant oflands in Aubourn to Elizabeth, wife of Walter de Colveville, theKing's enemy who is in prison. Elizabeth and Isabel are hermerely different forms of the same name, and the word 'late' inthe first passage is an error. V.G.

Most people have Isabel born in Muston, Lancashire.Unfortunately I find no record of a Muston in that county. Thereis a Muston in Leicestershire & East Riding Yorkshire. Of theseI believe that the Muston in Leicestershire is closest, althoughit is near Nottingham, not Lancashire.
