Tom, thank you for your information. I think mine were in Armstrong Co. Do you know if your John may have married a 2nd time? In the ledger of a store in Atwood, Armstrong Co. in 1871\72, it has entries for W. H. McLain, John M. McLain, Alexander McLain & Dorcas McLain. So I think the spelling was McLain instead of McClain but I could be wrong. Back then they spelled the way it sounded. The store in Atwood was Johnstons & Martins. It looks like it was a general store not grocery. My Great Grandfather or Great Great was the bookkeeper or part owner or something, since I have two of the old ledgers, AND they are old!! Where is the Monongahela located? Gin
