Your entry is correct I was one of the people who had the parents originally as Margaret Gunn & John Inkster(as you see it has been corrected). I was corrected by another long time Inkster researcher who found herself on the Orkney Islands. The Inkster lines are full of James & John's and it's pretty easy to make mistakes. As a direct descendant of James Inkster & Elizabeth Sutherland your imformation on their sons in also correct. I have them already in my file.
