Do you have an Archibald Shearer (1797-1867) married to Agnes Blackstock? Archibald and about a half dozen of his siblings immigrated from Lanark, Scotland to Peterborough County, Ontario, Canada about 1820, with one brother, James, going to Kansas. They were a very prolific family. If so, I'd be very interested in hearing from you. I have quite a bit of information on the family too.
