Hi! We're cousins! Second cousins, if I'm figuring it correctly.
My father, Edward Tierney, was Francis Tierney's son. Francis was the brother of Loretta. I have some more information, but it's presently in a format I can't read (upgrading to new Family Tree Maker soon...)
Anyways, the Tierney's came to Boston from Newfoundland. Patrick's father was Daniel Tierney. I've found the immigration for his wife and all the kids, but not Daniel. He may have died and the family then came to Boston. Haven't found when they came from Ireland to Newfoundland--the records are pretty sketchy. The earliest I have is Daniel's marriage in the 1860s? in Newfoundland.
I think I met your grandmother when I was young. Did she live down on Cape Cod? Yarmouth, Falmouth?
I'll try to get the rest of the info to you as soon as I can.
