I'm trying to track down ancestors of Sylvia Knight HOAG, daughter of Theodore O. HOAG and Charlotte Ayres HOAG. Sylvia lived in Troy, Rensselaer County, New York (born 11 March 1875). Apparently, both parents died when she was quite young, and she was raised by her mother's sister and her family. Many HOAGs in the area, but I can't seem to track down the right ones. Any help will be greatly appreciated.
