Thank You so much for Your reply. I thought this might be a dead end. The GALLAGHER cousins have been a challenge to trace. All of the other ancestors related to GALLAGHER through the DUFFY line were living in New York City. Only Mary DUFFY who married Patrick GALLAGHER in Phila in 1885, remained in Phila. Their youngest child was Catherine born in 1902 and married Your uncle Herman in Sep 1923.
I have only had contact with one of the descendents of the GALLAGHER family, and that was a number of years ago. Madlynne Biglin, who was going to gather info and get back to me. Alas, Madlynne has passed on and I didn't get any leads.
I do have information on where and when Mary DUFFY was born and about her siblings and cousins, if You know of Catherine and Herman's descendants and they are interested.
