I have just this moment found my connection, where my own line meets up. The Adam (b.1840) that you are looking for was my gg-grandfather's brother. My GreatGreat Grandfather was Stephen S. Fonda (b. 1833). He had two brothers that I do know of... Peter Adam (b.1830) and Adam (b. 1840). Is this the same Adam that married Marrie or Maria Paddock or a Margatet Boshart???
