Hi, would you be so kind as to provide the speculative information you have? p.s. do you have or have you seen the WO file on the Field Court Martial of W Cairnie, if not, I have photos of the file and could make these available if you want....
You would need to search the births on Scotland's People. I only had a quick look to see if there would be any clues about the name confusion. I may even not have found the right Peter Cairnie. There is a brief entry about him on page 145 of 'Shot at Dawn' by Putkowski and Sykes.
I will pm you my email address and would be grateful to have the documents.
