I'm looking for information on the descendants of Philander Pratt,b. ca. 1832 in Ontario,Canada, d. after 1900, location uncertain. He's living in Ellsworth Lake in the 1900 census, as a boarder - no family with him. He is the son of George and Olive Pratt and the brother of John Arden, Sr. and Addison Pratt. If you have a maiden name for Olive, it would be most helpful.
