My family was from Paisly Scotland, my father was Samuel Gallacher with brothers James (professional football player - goalie), William (Willy), David (Aberdeen), Robert (Robert ie. Bertie moved to Long Island, NY I believe in the late 50's)there were also some sisters (I remember that one lived in England) unfortunately I cannot remember all the names as most them had died when I was very young.
We moved to Canada in 1952 -
My mother was an Aird from Barrhead.
I don't know whether there was a Wardlaw connection or not - will need to check with my brothers.
I will try and find out more information for you.
