Success! I’ve literally just had a response from Fredericks daughter, Christine. She says: “Yes, Sgt. William Robert Louth is my uncle and I do have some information about him. He was married to someone called Kitty bur they had no children and she remarried. I tried to find out some information about him some years ago and had a reply stating that his body had not been found unlike the rest of the crew. As far as I know I, apart from my children and grandchildren, am his only living close relative. I am very interested in what is happening in The Netherlands and would be willing to do a DNA test if that was required. I would like to visit Muiden and see the grave. I know his name is on three memorials - Runnymede, Halifax and Humberstone, Leicester where he lived. Thank you very much for contacting me and please keep me informed. I will have a look at the websites from Muiden ” so yes, ‘Kitty’ must be the Kathleen referred to earlier. Good job everyone!
