Hi Madeline,
Thanks for the link. I went to that web page before but hadn't saved the link. I see 3 people who I believe are mine: Edward Cullen, Ann Cullen (Edward's wife,) and Mary Armstrong (formerly Mary Cullen.)
I find it interesting that there are no other Armstrongs besides Mary, considering the number of Armstrongs I have found in Albany. Does the organization that made the list go strictly by Irish surnames? I ask because while many Armstrongs lived for some time in Ireland, they are originally from Scotland.
I also see a lot of McMahons, but I have as yet been unable to zero in on a particle family that my great grandfather's second wife might have come from.
