Hi, this board is no good for you. This board is for the FreeCEN project which only concerns itself with transcribing the 19th century England/Wales/Scotland census and putting the transcriptions online for free.
If your ancestors are "Russian Germans", I suggest you try Poland boards, as prior to WW1, Poland did not exist as a state in its own right. Most of present-day Poland was control by either Prussia/Germany and Russia.
The other suggestion would be to logon to FamilySearch.org and look at the Germany/Poland/Russia/Prussia research guides.
Good luck in your research.
