Hi Ian. I have confirmed your info on Sidna Nourse, 1918-2009, from the Canada Voters Lists, 1935-1980. They show that she lived at 4 Johnson St with Gordon Beverly Nourse, 1917-1987, and that she was a photographer. Evidently he was her son tho’ I have no records to verify. The same Lists show Reginald Nourse and wife living next door at 4 Johnson St. I find it difficult to believe this was just a coincidence.
Clifford Bennett Nourse, Sidna’s husband, came to Canada from S. Africa in 1910 to study at the Ontario Agricultural College and stayed. The S. African Nourses are descended from Joseph Nourse, 1750-1802, a London wine and lace merchant. Perhaps your Reginald Nourse was descended from the Weston-under-Penyard, Herefordshire, Nourses and James Nourse who emigrated to the USA and died at Annapolis in 1784.
I also found from the 1963 Lists that there was a Dorothy Nourse (nee Maher), a teacher, living at the same address as Gordon Nourse. I don’t know whether she was his aunt or not directly related but she was born and died in exactly the same years as his mother Sidna. I also found from the Canadian Phone and Address Directories, 1995-2002, that there was a Gordon Nourse living at 6-D Johnson St in 1995, 1996 and 1997. I am left wondering who the husband of Dorothy Nourse was and where the 2nd Gordon Nourse fits in. Any ideas? Thanks. Steven
