He [Simon Tuchet] married Pernel (Pelronilla), probably daughter of Roger de CUMBRAI and coheir of another Roger of that name (b). He appears to have died circa 1203-05. His widow was living in 1218. [Complete Peerage XII/2:54-5, (transcribed by Dave Utzinger)]
(b) This latter Roger, son and heir, d. c 1213-14, when he was a minor. His heirs were Pernel and Agnes de Cumbrai, whose ancestry is not clear. It was from the de Cumbrai family that the Tuchets inherited the manor of Lee Gomery, Salop. The facts that Simon Tuchet m. Pernel, that John de Cumbrai granted him the manor of Willington, co. Derby; that Pernel de Cumbrai was eventually heir of Roger de Cumbrai, and that the Tuchets inherited lands from the de Cumbrai family, suggest that Simon's wife was Pernel de Cumbrai.
