I do not have a lot to tell.
Guy was born in Durham County Ontario about 1854 as seen in 1861 census ...son of Alpha Soper and Jane Mallory.
His wife believed to have been Sarah McDougald born 1859 Canada died 14 Dec 1898 Caseville Huron Michigan. A birth record shows a son Alpha Benjamin Soper born 16 Aug 1886 Thunder Bay Ont. Beyond that I have nothing but 2 of his brothers ...Timothy and Alpha lived in Michigan
