My great-grandfather James Nelson was born in Derry, Cavan on 18 Apr, 1832 (according to his US Naturalization certificate). His parents were Thomas Nelson, b. in England, and Rosanna McDonnell, b. in Scotland.Does anyone have a connection with James? I traveled to Cavan a few weeks ago but the only information I found was for a David Nelson, b. approx. 1855, his wife Jemima Niblock, with son Matthew Nelson, b. approx. 1884.I don't know if this is the same family but was the only Nelsons listed in Derry, Cavan. If anyone has info on this family (David and Jemima's marriage certificate) or other on the Nelsons in that area, I would much appreciate.Thank you.Marilee C.
