Re: richnow ancestors
Ok, I have read the original ship manifest at Ellis Island and the place where they came from is RIXDORF, not Ricesdorf.
Rixdorf is now Neu-Kölln and is part of Berlin.
Here are some informations:
Familysearch has churchbooks of Rixdorf on microfilm.
Cause you have some correct dates you will find out more.
Only German, sorry:
In 1737 some Czech people settled there. These were Protestant refugees from Bohemia.
Cause the name Richnow is not a typical German name, it may be your ancestors were from Czech.
Churchbooks will tell you more.
