Just saw your posting. I've just begun work for a family member. It just so happens that his grandfather's name is Paul Dancsak, pronounced Danchak. The name has been altered quite a bit. You should check the other message boards with the alternate spellings.
Paul Dancsak or Danczak we believe, was from Hungary. He had 3 sons that we no of. Names...Arthur, Rudolph and Joseph. We also believe them to have been born in Newark, New Jersey in the early 1900's. Would also appreciate help with this family.
