OneGreatFamily.com are where I went back the farthest. They have neat relationship calculating tools. They have over 88,000 in my tree. Even the help desk there was shocked. I guess it's not that common to have a more complete tree. When all the famous names started popping up ,I googled and double checked records. It was really humbling and exciting for me. It makes it hard when people start doing the prove it game, but I know I did solid research and checking sources. The best of luck to you. I find my Irish research hard too.
