Hello, Mansel George Cattroll was my great-grandfather, too (with Kizzy) and his eldest daughter, Eva Sarah Louise, was my grandmother - she married Alfred Westwood. As I have only just seen your message, along with Caroline's (Kizzy) and Michael, I don't know if you will still be researching your family tree.
I live in Swansea (Morriston) so have quite an extensive tree, which I have researched with the help of Michael and Caroline. If you would like to share my tree with you (it's Private) I will be happy to co-operate and send you an invitation (and vice-versa with your tree).
Let me know what you want to do.
