I came across your post while nosing around looking for Cain Mahoney who I think was born in 1904. I know for a fact that my Dad's Great Uncle Dan was married to your Joan Foott (your post of June 24, 2010) According to Griffith the Mahoneys and Foottes were neighbors in 1850. There are six children in the family, and Mom's name is spelled six different ways. I have found reference to Cornelius Footte as the tenant next to Cain Mahoney in the Griffith's Valuation.
I am descended from John F. Mahoney, born in 1857. I have been at all kinds of family things with Margaret and Mary Mahoney, Joan Foote's Granddaughters.
If you feel that it would be worth your while, let me know and I will send you what I have.
