Hello Emily, thank you for your reply which just arrived as I was on line. You have given me a good clue as Barton on Irwell is the location where my Jack Nolan lived. There was another of Jack's brothers called Peter who was in the same area. He married Mary Fitzgerald in 1916. I am 99.9% certain that my Jack Nolan married and his first wife died. He didn't marry my Grandmother until the late 1930s and it was the second marriage for both of them.
May I suggest that you reply to my personal e-mail address at firstname.lastname@example.org
as I have quite a bit of info. I can send you but as I am no longer a member of Ancestry I find using their boards quite difficult.
