I am searching for any relatives of Frederick, Gerick or Christafur Au. I am a direct relation of Christafur. He changed his name to Eye.
These three brothers arrived in Philadelphia on October 23, 1754 on the ship Recovery.
I am trying to trace my family's roots to where they came from in Germany. I am looking for any type of birth records or document that may list where they came from or who their parents are.
I would appreciate any information leading to the answer to these questions.

Thank you for your assistance.
