Hi - The two others in the photo are still living so I can't name them but the lady is the sister of John Dalton and the man her husband. The older lady on the extreme left is John's Mother, Mary Ellen Bonas (nee Dalton) born 1907 in King St, Wexford Town.
John was born out of wedlock around 1926 in Barrack St and raised initially by a Fenlon family (A Luke and Bab's Fenlon - also in Barrack St per DUKESLANE)
I also understand from DUKESLANE that Maggie Fenlon had 6 siblings, Richard, Mary, Martin, Jack, Luke and Katie - all deceased. Which part of the family do you decend from?
