I am also interested in learning about a Martin line from Montreal. My mother's grandmother used to tell her the family owned the land where Montreal is now. My gg grandfather Francis Martin b. abt 1840 in New York. Lived in Constable, NY in 1860. Married Clarissa Marshall around 1859. Served in the Civil War - 14th Reg NY Heavy Artillery. He either owned or worked at a sawmill. Any info would be greatly appreciated.
