Hi Chrisw

Elaine is correct.

There is a link to a map portion you can download below:

As I have uplaoded the image as a guest the image will not be held for long.

It is taken from The National Library of Scotland site:
https://maps.nls.uk
which is an extremely useful resource for historical maps.

Kind regards
