Hi Monica
Thanks for that information

- I was thinking along similar lines but not quite

-
What you suggest is very plausible - that Andrew was Walter's fathers name I will go looking for those names around that period

.
Another suggestion that someone has made is that given Walter and Isabella were married in Langholm one of them must have been born there - probably Isabella - because usually you married in the parish where you were born - does this sound right?
Although I have never been to either Langholm or Canonbie I understand that Canonbie is the larger town and the Nittyholme where Walter and Isabella lived most of his their lives is somewhere in between the two.
Thank you again for you suggestions and to everyone else I finally feel I am making some progress

This is where the other genealogists in the family got stuck too!
