Thank you everyone for your contributions. I was hoping that it would be Kathleen Shelton, but unfortunately there is no one to ask any more. I have tried tracing her line in my family tree, but I get stuck at her grandchildren. I think that I have found four, but at least two have passed away. They all have an eastern European sounding surname and that is where I am hitting a brick wall. I obviously can't post their names, as they may have living family members. Hopefully, one day, I may solve the puzzle as to who Kathleen is.
