Chuck and Mike,
My grandparents were MIchael and Mary DeZuba (or Dzuba). They immigrated from Uzgorod and settled in New Milford, PA where they raised 12 children (Mary, Michael, Joanna, Margaret, Charles, John, Julia, Nick, Stephen - my father, Peter, and 2 more whose names escape me).
My uncle Peter later took the surname Thor as he discovered that Dzuba was actually his father's stepfather's name. His father's birthfather died before he was born and the son assumed the surname of his mother's new husband - Dzuba.
My father settled in Binghamton, NY, and we were always vaguely aware that there were other DeZuba's in the area that we might be related to. In fact, my brother Michael attended a funeral this past year for a DeZuba we had never met. I'm guessing this may be your branch of the tree.
