I am looking for any information available on Mary Swallow born about 1830 in Philadelphia. She married my 3x great grandfather Daniel Shaw on July 6, 1854 at the Calvary Episcopal Church in Philadelphia. I have a feeling she died before 1870 but I have not been able to find a death record. Also, I can determine the names of her parents or siblings.
I have reached a road block in my research on both Daniel and Mary and would appreciate a push in the right direction.
