I am researching the genealogy of my Gilmour family line. My great great grandfather, David Gilmour (1787-1881), from Strathaven, emigrated to Glover Vermont 1847, 7 years after his son Arther came to the USA. David's parents were Arthur Gilmour (d.1759) and Margaret Russell (d. 1763). Both lived in Strathaven, Miln, Lanark Scotland.
I have not been able to trace my Gilmour ancestry beyond that, and have not been able to establish the possible link between the Isle of Lewis and Strathaven.
