Thank you csc, Wigtown was my first thought but I have been unable to find any births that could be him. I have found an Alexander Grierson born 1762 at Bowden, Roxburgh on IGI, but I am sure he isn't mine as he is included in other trees. By 1851 the Griersons had spread far and wide, but Dumfries was their place of origin. There were Griersons in Cumberland for the English census 1851, but I have been unable to find any siblings that were born in Wigton.
I am hoping that someone that knows Dumfries well may be able to come up with a local locality that conforms with the census registration of Wigton, Dumfries.
