Just touching base with you on this family line. Still haven't found anything new, except on my grandmother's side. We always thought her maiden name was "Dailidonis" but it is "Dalgidonis." Ellis Island Records show the family coming over June 19, 1906, and that they were Russian/Polish. We have always been told that my grandmother's family was Lithuanian. You are so good with the names, dates , and borders - I think Lithuania was under Russian rule at that time, and maybe my grandmother's maternal side was Polish. No one has ever heard mention of that.
And on a plus side, I found a second cousin on my grandmother's side just today!! We are going to trade infromation - his sister has all the family papares and a huge photo album!!
Is "Beca" Czech? I live near Dallas, Tx - how about you?
