Ron I must have been half asleep when I posted! You had already posted most of the questions I asked! What I'm trying to figure out is if your Jacob and my Catherine came to the USA at the same time. If Jacob immigrated here then they both had children at about the same time and arrived at the same general time and place.Three of Catherine's children were born in Germany, one in 1822. If both adults brought their young families here you may find your proof through a connection between Jacob and Catherine. It's an avenue to explore anyway. Catherine m. Christof Schreiber or a variation of that spelling in Germany. Hope this lead pans out, let me know.
