e-mail me using the address on the Kauffman surname project at familytreedna.com . If you can include your yDNA results for ages ago and which family line you matched into we can discuss some options. My Kauffman line is the major Kauffman group within R-U106. There are 2 much rarer and more recently tested Kaufmann lines now within the R-U106 haplogroup region. Also provide your paternal kauffman line. My extended Kauffman family line now contains 3 other colonial period immigrants in addition to immigrant Michael and immigrant Jacob Kauffman. There are hints there could be another 1-2 lurking out there without solid paper trails or test results available.
