Amazing how many of these names are in my Watt ancestry, too......wrong dates and wrong parents, however. I do wonder if they could have been related a few generations back, though. They seem to have been in Lanark for a long time.
My Watt g-g-grandmother, Isabella, married Joseph Bradfield and returned to his home in West Yorkshire in about 1802. Her parents were Thomas and Isobel Rodger Watt, with his parents being James Watt and Euphame Barr. I have her family back farther, but haven't located parents for James as yet. He was born in Cambusnethan, Lanark.........perhaps there is a film for the parish records I can look at.
