Modern judaism teach about certain religious men called Bnei Noach, however as far I know there is not any textual or archeological evidence on such a group of men. I have attached a very interesting paper deals the archeological evidence on God-fearers".
Rabbi Dr. Williams Pitter

archaeological evidence
Just to add to Rabbi Pitter's posting of a paper about the 'God-fearers': Kraabel is perhaps too critical in attempting to dismantle all the evidence for God-fearers. See this more recent paper by Joshua Levinson.

Thanks very much Profesor Cooper for the Levinson paper.
However, Dr. Levinson paper did not give any strong argument in
relation to the existence of benei Noach as a community of "God-fearers".
Greetings: As many tribes of Jews from the children of Jacob do not find such a name, and the possibility there is confusion or similar
