Thanks! I had seen that information, but have also run across a line with a Gustavus in New England. Haven't found a connection yet to say they are the same one, but still looking. There are records in German from Germany available from Ancestry for the Kneistrich family you mention that have a coat of arms, etc., but I was unable to translate much of them. I found a lot of legal records for the Kanesters in Virginia too, especially in the Winchester area. Family legend has it that the lineage information was in a family bible originally belonging to Gustavus, but no one seemed to know the whereabouts of this since the 1800's. The branches of the family I have heard from all have the line beginning with Gustavus and probably a brother who came from Germany.
I have also seen varying information on John Henry's wife. One line even claims a connection for her family to Pochontas, but I rather doubt that. There is some discrepancy even as to her family name.
If I find any new connections, I will post them.
