Sounds like the same guy, and I think I have the same photo, they have funny fur hats on, I think the older guy is his father inlaw from what I've been told. Are you on facebook? Matilda is also related to me. I was actually adopted as a young child, but have since found my parents and these William is my fathers, mothers grandfather. I have quite a lot of info about him, but am unsure if there is a jewish connection. I would be thrilled if there was, I have always had a special place in my heart for the Israeli people. http://trees.ancestry.com/tree/12043486/person/-342009753
