My great-grandfather was Archibald Shaw of Paisley. He was a slater and founded a business there. It still exists, except now they call themselves roofers. It is still there on Canal St.in downtown Paisley. You can find it (with full
address) on the Internet. The business name is: A. Shaw, Roofers,and in each successive generation the eldest son got a name beginning with A. to perpetuate that name. My grandmother, Katherine Shaw, nee Ross, migrated to Findlay, Ohio. Her son Joseph Tooley of North Findlay is still alive and undoubtedly knows more than I do. Right Archie Shaw?? Your guess! Good luck. G.F.
