Well thank you very much. I don't know what you can find or where you could look, but I'll just throw out what information I have.
James John Middleton was my uncle and I have a letter he wrote to my mother undated but certainly well after 1918, as he writes as an old man with aches and pains. This was with address 728, Norah St. Fort William.
The 1921 Census however shows him with wife and son James Henry born 1917 (not 1817 as I had shown) at 1105 Edward St. Ward 4 Fort William.
Of course I'd like to know of any other progeny of James John or James Henry.
While I appreciate you kind offer and am grateful I must insist you not put yourself to any trouble.
Perhaps if there is a FHS that you could identify I could follow up.
Thank you once again
Don
