I added the information found in Jones (1985). There is a record of confirmation, and it says he married Catharina Launhardt. No marriage date, list of children, nor info about his second marriage to Sarah Cook, but I added this info from his FamilySearch Profile.
In "Even More Palatine Families" (2002), volume 3, there is a large amount of newer research about the origins of this family, reported by Claus Petry, a collaborator with Jones. I will add this info to the relevant profiles, but it concerns earlier generations in Europe, not John Traber (b. ~1720- )
