I have been trying to find information on my mothers family for ten years or more and keep coming up with nothing. This is what I have.

His parents are August Dorn and Appolonia Capelli . I have no other information on my great grandparents.

Philipp Dorn married Elisabeth Amelia Gunther in Germany DOB. 03 Mar 1891. DOD 02 Jul 1935 in Statin Island NY. Elizabeth's parents are Bartholomaus or Berthol Josef Gunther who was from Buttstedt, Germany.
Her mothers name was Emilie Naujoks or Augusta Emilie Naujocks who was from Memel, Germany. (Prussia). Gunther and Naujoks were married in Braunschweig Germany.
