I've just been speaking to my Dad. He said that your Mum's long term memory is very good and that you only live a short walk from her. Maybe you should go and talk to her. She is bored out of her brain in the home and doesn't get many visitors.
I think it will be easier to find out about your dead relatives from your living ones, rather than a website!
Good luck with your search and I hope Carrie & Jenny are doing well.
