I'm not sure if the Vlachs I have in my tree are of the same line or not. My great-grandfather was James Joseph Vlach, b 1872 d 1930 and he was married to Barbara Vlna, b 1875 d 1938. Both James and Barbara were born overseas I think but I don't have locations. I'm not sure about siblings but I know that he had a son (my grandfather) named Frank, a grandson (my dad) named Frank and a great-grandson (my brother) named Frank. There seems to be a lot of use of the names James and Frank associated with the Vlach name so I'm not sure if those are matches or just similarly named people. If any of this rings a bell with anyone, please let me know.
