I did not find that any of the Roos name came from the Faber family to America. But that is not to say that some did not. That is a popular name in that area. There could have been cousins that came. Maria Roos Faber died in Pfersfeld in 1840. She was married previously according to the marriage certificate, but the German Rheinland-Pfalz script is hard to read from that time frame. It does not mention the two previous children's name. Her father was Eberhard Roos.
