My 3rd great-grandparents Patrick Devine and Emily Sheldon are still missing. I have no idea where they are after the 1875 NY state census. I think they divorced and I think I found Emily in the 1900 federal census, I'm 98% sure. I think she might also be the same Emily that I found in the 1905 NY state census. After that she is a mystery like her husband. I won't give up.
