General Notes

He [Ralph Basset] married 2ndly shortly before 21 July 1295, Margaret, widow of Urian DE ST. PIERRE of Peckforton, Horsley, &c., co. Chester. He is said to have died 1322.  [Complete Peerage II:7, (transcribed by Dave Utzinger)]

Note: I wouldn't be surprised if the manor of Cheadle came to Ralph Basset through his marriage to Margaret.  He certainly acquired it after the marriage.  It might provide some clues as to who Margaret is.  I believe that the manor then descended through John Basset, son of Ralph & Margaret.
