Sarah Cannuff/Canniff married James Carroll, they were both born around the 1820's in Ireland, and settled in New York. I can't find them on any of the 1850/1860 census, but my ggrandfather John was born in New York in 1848. John married Margaret Murphy and they lived in Piermont New York in 1880. Margaret's parents were William Murphy and Mary Connell and they had 3 children. Margaret, Jeremiah, and ?. I still can't find them in any New York census? Wish I knew what to do next. They came to states before Ellis Island
like most of my Irish ancestors all before Ellis Island.
