Notes for: Roger de Wycliffe
The name of this Wycliffe comes from a Wycliffe pedigree in The History of Yorkshire; Wapentake of Gilling West, by Marshall General Plantagenet Harrison (1885). I don't know where Harrison got this information. I can only assume it is guesswork on his part from looking at old records. Harrison's pedigree seems to be the only one that goes back this far; so I will go with it for now.
About Roger de Wycliffe, the pedigree says Lord of Wycliffe in the time of King John, was po. le/lo (???) for Mabilla, the wife of Thomas de Multon, 26 Henry III., in a plea of land against the Prior of Norwich, and po. le. for Thomas de Multon 27 Henry III." The pedigree says Roger married Margaret, daughter of Thomas de Multon.
Information (no sources) at WorldConnect listed Margaret de Multon (b. abt 1199) as Roger's wife and that they married in about 1218. Margaret was listed as the daughter of Baron Thomas de Multon (b. 1175 in Multon, Lincolnshire, d. 1240) and his second wife Sarah De Flete (b. 1180, d. abt 1204). Her father was indeed Thomas de Multon, but I don't find collaberating information about her mother being Sarah de Flete. Roger was listed as born about 1193 in Wycliffe. That is probably a guess.
