Hi
I hope I can add something useful to this thread and perhaps glean some information for myself.
I've not read everything on this thread but was drawn in by the parts about Susan Foy (McBride) and her Mother Sarah Foy.
Patrick & Sarah Foy of Russel Row, Bathgate were my paternal great great grandparents.
I have some papers about their oldest daughter Susan (32 yrs old at time of 1901 census) married to James McBride.
Their son Myles (4 at time of 1901 census) joined the army in 1915 and died 25.8.18 of 'exhaustion' as a prisoner of war in Kaehmen, Crossen.
Her address was given as The Loan, Torphichen, Bathgate.
I also have an old photograph with no information on the back other than 'Mays Grandmother'.
It's highly likely that this was May Foy (born 1914) whose paternal grandparents were Patrick & Sarah Foy of Russells Row, Bathgate
It is however possible that the lady in the pic is on her mother's side. That would be Helen O'Donnell. She was the wife of Patrick Foy Jnr (Balbardie Avenue, Bathgate)
It's a long shot but someone may be able to confirm the identity of the lady in my picture.
Sarah Foy (nee Cannon) ?
