That photo was always at home. I suppose my mother brought it with her. The Daniel Linehan in the photo was her grandfather. Nancy Forrest Linehan was her grandmother. Nancy & Daniel's daughter Catherine Forrest Linehan was her mother - my grandmother.
Written on the back of the photograph is
"Catherine Forest Lenihan
I assumed this to be incorrect as I thought the lady was too old to be Catherine. However looking closely she looks very good for 50+ maybe 60? The style of clothes etc may be making her look older.
I'm not certain but currently I have them as father and daughter but am open to persuasion.
