Hi Trish, Brian, Tim,
I also have that photograph, the couple are husband and wife, Daniel Linehan and his wife Nancy Forrest of Ballynaguila, Tullylease. They are my great great grand parents. I am interested as to why you think she is his daughter, in the 1911 census he was 70 and she was 57. Also I thought I had the original of the photo, how did you come to have your copy?
