I am interested in your William Boag as I hope he may be connected to James Boag born about 1804 in New Monkland, Lanarkshire, Scotland. His parents were John Boag and Margaret Williamson but I do not know of any other children they may have had. James married Jane Nielson in 1829 in New Monkland and I know that other members of the family came from Uphall West Lothian.
Could there be a connection?
