Agnes,
thanks for your help on this one, the one who is the butcher is sadly no relation of mine. I have John sailing to Boston on 7th March 1911 from Liverpool on the SS Ivernia. He was going to visit a friend Robert Mutch at 521 Patrick Street, Barre, Vermont and gave his contact address back in Scotland as 1 Farquhar Place Aberdeen the address of his mother.
The next sighting I have of him is when his mother Elsie Gordon Allan went to Barre Vermont in 1914, she gave him as point of contact at 38 Long Street, Barre, Vermont.
I have failed to find John on the 1920 Census, I think that this is because he is back in Scotland, his brother Alexander stayed at 18 Jute Street, Aberdeen yet a year later in 1915 the tennant is now a John Allan. This may well have been because Alexander was away fighting in WW1 and his wife moved to Newmilns in Ayrshire to be with her folks.
I have searched the Commonwealth War Graves and cannot find a John Allan that gives any contact detail for Aberdeen.
John's brother James took his own life in 1935 and in his obituary it mentions his two brothers and one sister in America. We know that James's sister Jane Ross Burnett was in Barre and we know that Alexander was back in Philadelphia after 1921 after returning from the war. His two other brothers, Bob ( My Granda) was back in Scotland and his other brother William was staying outside Aberdeen. So the only obvious conclusion is that John has returned to the U.S.A........unless however this is a total red herring, yet we cannot find his death in Scotland so he must have died abroad.
Please feel free to pitch in with your thoughts,
All the best
