There are books available that list German immigrees to Philadelphia Harbor, but most only contain the names of adult males who also took the Oath of Allegiance shortly after the ship docked. Would there be a go-to place in Rotterdam, or more accurately within Germany, that might have listings of all passengers who sailed? I have referenced information that my ancestor, Johann Heinrich Fuchs, came to America in 1749. It is very possible he came over with two sisters and a younger brother. The list of adult males for the Ship Two Brothers, Sept 1749, lists a man by this name, but research done on the German side, and detailed in the book "Westerwald to America" has information this was a different Johann Heinrich Fuchs. This person came with a brother Johann Adam Fuchs, and both had their respective families with them. There was a second ship in September, the ship Dragon on the 26th, does list a Johan Heinrich Fuchs.
