Think we need a little more direction now on where the searches need to go on the Shaw side...
This was the original post to get back to basics:
Looking for Samuel Shaw and wife Mary. Samuel had a son born 16 Feb 1818 by the name of James. James married Grace Clingan. They came to Wisconsin USA in 1855. On cemetery stone it reads James Shaw Dumfries and Galloway, Scotland. It said on stone for Grace 1824/10/2 for birth. It also mentions Parton,Kirkcudbright,Scotland on some information. I cannot find Samuel or Mary on any documents in Scotland. It states in a book here in USA that Samuel was a livestock buyer in Scotland and died in Scotland.
From what we have seen, Samuel Shaw was a farmer at Boghall. Livestock buyer would fit with the occupation of farmer. He shows in Crocketford at the time of his death. His death registration will be available to view on
www.scotlandspeople.gov.uk This should include his spouse(s) names and his parents' names if known to the informant to his death. If Nicholas, wife died in Scotland, her details will also include her parents' names if known to the informant.
We are seeing his wife as Nicholas, not Mary. He may have been married prior to Nicholas.
Going out sideways with siblings can sometimes help with different type of connected info re parents etc ( CAMPBELL, Robert - M11/12/1846 - At Boghall, Kirkpatrick Durham, on the 11th inst., by the Rev. Mr Greig, Mr Robert Campbell, farmer, Duchrae Mains, to Miss Margaret, second daughter of Mr Samuel Shaw, farmer, Boghall.
