I really appreciate your insight. I am a beginner at all of this and unfortunately I only have smatterings of info that may or may not be correct. I have Johann Philip Karriker "Karcher" being from Palatinate, "Germany" in c.1680-1690 and Anna Maria Reeb presumably being from the same. I don't have where they died, but they may have come to America because their son Philip Carriker died in Cabarrus, North Carolina. I only show that he was born in c.1720's in Germany. He married an Anna? Christina Eisenmann who was born in the 1720's or 30's. They had a son named Philip Carriker b.1757 in PA who married Eva Goodman. Unfortunately, I don't have more specific areas than that for their births.
Do any of these people show up in your research? Sorry about the vague details, but I appreciate you trying to help!! Best regards, Jamie
