I have no information on Mary Nacey other than she had a child, Stephen D. Connell -573, with my Great Grandfather, Denis Connell-559 in Washington DC in 1860. 1860 is the year that Denis married Catherine Rover on August 24. There is also the possibility that Mary was born in Ireland.
There is a birth certificate from St. Patrick's Cathedral that states Stephen D Connell is the "lawful child" of Denis Connell and Mary Nacey. Stephen is buried in the Connell Family plot which has lost all of it's beautiful tomb stones. What remains is a flat marble marker for 3 of the Connell's daughters.
I have nothing else to go on and would like to know more about Mary and Stephen.
Thank you
