Have done the Griffiths evaluation and found a Patrick Basquill in Kilbride also a Catherine Basquill living across the road from him. Not sure where to go from here though.
Thanks for the link about the flour dealer too, can't be too many Patick Basquills about at that time, so could be the one
I will look into the soldier, that could be useful, though there seems to have been quite a few Basquill families turning up in Stockport at the same time
