Hello, cousin! For the sake of other DERRY researchers, I will report the following BASIC info that your Ellen Bridget DERRY, (b abt 1835 in Ireland; d abt 1912), married Benjamin Cornell (himself b 19 Mar 1822 in Caledonia, Livingston, NY and died 30 Apr 1899 in Saginaw MI). They had at least 9 daughters! - all born, I think, in Lewiston, NY.

Ellen Bridget had siblings:
JANE, b abt 1829, Co. Derry, Ireland, and married Michael Joseph McANDREW of Crossmolina, Co. Mayo, Ireland and raised their family in coal-mining Girardville, PA.
THOMAS Derry, b abt 1830 in Londonderry, Derry, Ireland and married Mary Elizabeth GAREY (b abt 1837 in Marine City, MI)
MARIAH (b Jan 1834 in Derry, Ireland), married Mark Clair. Mariah died aft 1920 in Iowa City, Jefferson, Iowa.

We'd love to meet other DERRY descendants from this branch, who came into USA through Canada in the early 1840s. Regards, Mary W.
