My name is Edwin Paynter, I have family from the Detroit area and from London, Ontario.
I dont know farther back than my great grandfather and don't know the names of any of his siblings, but your story sounds pretty familiar.
I do know that my father's cousin owned the Grigg House hotel in London in at least the 30's and 40's, as he would often travel up there to visit.I am unsure of how long that hotel was in the family, and I don't remember my cousin's name, but from what I understand, he was rather well known in the city of London.I will see if I can find out.
Anyway,My great grandfather is William Patrick Paynter born in the late 1800's, father of William John (born ~ 1906), Walter (died young of whooping cough), and Clarence Paynter.
William John married then divorced Elaine Warner, and later married Marjorie Tenerowicz, the daughter of Rudolph "Doc" Tenerowicz (mayor/congressman from Hamtrammick). William John fathered 8 children, one of which passed away as a young child in the early 1940's. Surviving children are Sally, Walter (my father), William, Thomas, Michael, Marjorie, Samantha.
If you could fill in a bit, that would be fantastic!
