Where is Galston located? You mention Torrance being in business. I was reading old newspapers online for the Glasgow area in very early 1800's and their were a couple articles re: partners William Hamilton and a man by name of Torrance. Can go back and locate if interested. I think it was a furniture or cabinet business, but I could be mistaken. I am researching the names Young and Hamilton in Barony, Barachnie, and Rutherglen.
