The origin of this family remains obscure. They held land in Morley, near Wymondham, Norfolk, and in Roydon (Reydon), on the north bank of the Waveney, the boundary between that county and Suffolk. That their name was possibly assumed after marriage with an heiress of Morley is suggested by an undated deed of Robert de Morle, son of Randulf de Charun and Maud (---), granting the rights of himself and his mother in certain land. Randulf de Charun figures in the account of the sheriff of Norfolk in 1159, and in 1166 held 3 knights' fees of Hubert de Rye in that county, 2 fees in Bucks, and one fee in Beds jointly with Richard FitzRalph and Osbert de Clinton. The family of Charun were early associated with Roydon. Odo de Charun, in the reign of the Conqueror, gave to the priory of Eye two-thirds of the tithes of Gislingham, Suffolk (about 5 miles south of Roydon), and of Roydon.
ROBERT DE MORLEY, very possibly the Robert abovenamed, was party to a fine in 1199 with regard to common of pasture in Bressingham, Roydon and Shelfhanger. [Complete Peerage IX:209, (transcribed by Dave Utzinger)]
Note: The CP entry for son Matthew indicates that Robert's wife was a sister of Bartholomew de Mortimer (being Matthew's uncle).
