I have two places where the BOHREN family ties into my KAUFMANN line, but it is long before our families immigrated. My 7g-grandmother was Elsbeth BOHREN b. c1673 probably in Grindelwald, m. 1690 in Grindelwald to Bartholome "Bartsch" Sr. KAUFMANN. They had 13 children that I know of. My 9g-grandmother was Elsi BOHREN b. c1620 in Grindelwald, m. 1640 in Grindelwald to Christian Sr. KAUFMANN. They had 9 children that I know of. However, I haven't found either of their parents or any siblings yet, so I don't know what, if any, connection there is to your BOHREN family. But in looking for them I have noticed several other BOHREN women married in to the KAUFMANN family as well (some in the mid-1800's), so I will try to post it if I run across any interesting info concerning connections between the two families.
