I am looking for information on Andrew John Smith born about 1848 in the Hamilton, Ontario area. His parents were John Smith and Mary Gillespie, both born in England. He was a machinist and he married Tillie Forster in Canada in 1875. She was born 1855 in Canada. They had no children. He first came to the U.S in 1869 and lived with his brother in Venango Co. In 1880 and 1900, the couple are in Edenburgh. In 1910 Tillie is a widow living on her own. Could someone please give me some advice on finding dates of death for these two people. Regards, Virginia
