Notes for: John 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 this John, the pedigree says "John de Wycliffe de Ulvington, surety for his brother Robert in a plea of land 8 Edward I [abt 1280]." He married "Juliana, a widow 30 Edward I [abt 1302]."
