Sorry to hear someone claimed all your hard work. I myself have spent days compiling my tree with help from close family members.It's always rewarding to find a long lost relative but for them to claim all your efforts is just not done. I don't blame you if feel reluctant to open your tree. Anyway I think my tree is linked through my sister-in-law Margaret Patricia Wolf 1936-1992 her ancester Thomas Birchall 1859-1940 married Ellen Pilling 1864-1946. I have quite a full tree of information on this branch of the Birchall family which does not link to my Birchall tree.I don't wish for any information from your tree onlyan acknowledgement of a link to your tree. If can provide any help in your research please let me know.
