I am looking for a source to prove that Lansing Fonda, b. 03/21/1789 Albany Co. NY is the person who married Pheobe Germain and had children Eliza C. b. 1824, d. 11/08/1883 in Waterford, Saratoga Co., NY and Martha b. 1830, d. 10/21/1886 in Halfmoon, Saratoga Co, NY. I have spouses for both children if needed also. I am trying to prove also that Lansing's parents were Douwe Fonda and Machtel Lansing.
