One of my ancestors was George Iddeson who lived at Kirkby Malzeard (a few miles north of Ripon) after his marriage. This was in the late 18thC. There were earlier Iddesons at KM, but I can not find a connection.
George married for the first time in 1765, at Ripley near Harrogate; his name was spelt as Edeson in the registers. There were other Edesons/Etesons at Ripley.
At Ripon there were Eedsons/Eadsons.
I am wondering if George came from Leeds and his baptism was 26.11.1740 George son of George Addison. There were also Eddisons at Leeds.
No William Iddeson.
