Hi! I was excited to see your posting.I believe that we may have a link.
Andrew V. Ammerman is my great-great grandfather.He was married to Elizabeth Van Tyne? (not sure about the last name, we've never been able to confirm it)According to my information she was born in Jan 1824 in New York.They had six children, John Dewitt Ammerman being the second, who was born abt. 1855 in Almont, Michigan.
John Dewitt Ammerman, my great-grandfather, married Jenniw Mooney in 1884.
If this confirms any of your data, I would like to receive whatever information you have on the Vantine family.
