Hi Alexandrina!
I have seen your name on a Blog relating to the Borders' Murrays but haven't commented there because it doesn't seem to be active at the moment.
I really struggling with 'my' James Murray Born in Yarrow because I am unable to identify his parents!
He was not born in the middle of the 1700s as you say though but in the last quarter. I am assuming that, given the traditional naming patterns, his father is likely to have been called John who would, indeed, have been born in the middle of the century. After that I am clueless. I feel sure that the family are not descended from landed gentry as there is no sign of money anywhere so they will just be ordinary working people.
There are so many James Murrays born in Yarrow in the last part of the 1700s but if his age is correct according to later Censuses then he must have run away to join the Militia- even under age! He was married young too!
If you know of any John Murrays through the Murray family contacts you have who were born about the middle of the century-name of wife unknown (if grandchildren named for her then could be Christina or Helen) I would be grateful for any help.
Kind regards
