Thanks for the offer foxglove. William was born in mid Norfolk, probably the parish of Reymerstone in the district of Mitford and Launditch (Great Witchingham and Dereham were the biggest towns in the area). All his siblings were born there. He signed over his farm in 1832 and left for Canada almost immediately. His fathers will of 1813 says he was married, but I've not found any further reference. He was probably born between 1785 - 89.
Separately, a closer relative Oswald H. Reynolds born 1893/4 in Norwich, Norfolk was last heard of living at 47 Mahoney Ave., Toronto No. 9 in 1941.
He had a daughter Edna, and I think sons Sid and Cyril. I don't know when he left England. He did work for the Prudential Insurance Co. of America.
