One of my ancestors, Ellen C. McDonald, was born in 1847 Philadelphia. She married A Patrick Seery who was born in Ireland, per their son's death certificate. They had at least 2 son's together, both named John ( one died as a child) who were both born in Wilmington, DE (1870 and 1876/1877). I have both of their death certs and also Ellen's from Delaware.
If this is a hit for anyone researching Seery's please let me know. I'll be more than happy to send you what I have. Plus... There's a woman named Melissa Gordon who I am in contact with who is a descendant from Patrick Ellen's 3rd child (the name escapes me).
