I'm looking for any information on the Drnach's/Drnac's. My great grandfather Vincent Drnach emigrated from Slovenia and entered America in July of 1912. I believe the "h" was added to Drnac upon entering through Ellis Island. There was another source that said his father's name was "Vinko Dernac" but I do not believe that is reliable. I'm not exactly sure where he was from, I believe it was Ljubljana. That's all the information that I have, does anyone know anything?
