I did do global searches on the many ancestry sites I used which even brought up Eileen Haydons in Canada and the US. There were no exact matches for her (or James/Gertrude Haydon) in any of those searches that fit the correct time frame.
I have considered that none of what I thought I knew might be correct about her life in England. I only have pictures after she left there. She did tell me about her street, house and the church but they were rather general descriptions.
The similarities in the names and dates pertaining to the Pinches are compelling. If I do get to the point of contacting any of the descendants I think I should start with the grandchildren and find out if they know anything. I'm afraid what it might do to the son if this is true. If anyone has an address on either of them, please send me a PM. Thank you again.
