Some of you may be aware that we now have three paper descendants of Jacob STROUP of Lincoln [now Gaston] Co., NC, tested for the STRAUB Y-chromosome DNA Surname Project. If you are, you know that two of the test subjects were Haplogroup I1a and tight genetic matches to the descendants of Johann Pieter STRAUB, 1733 immigrant to Philadelphia, but that the third individual was a decided non-match to these two. The third individual is Haplogroup J2, meaning he cannot have had a common ancestor with the other two for tens of thousands of years and meaning that he apparently has an NPE ["Non-Paternal Event," i.e., a hidden adoption or illicit paternity] in his lineage.

This individual descends, on paper, from Jacob's son, Adam STROUP, on this line:

Jacob STROUP I & Maria FRENSCH - Haplogroup I1a
_Adam STROUP & Catherine ALEXANDER
__Jacob STROUP II & Sarah JENNINGS
___Andrew Jackson STROUP & Mary Ellen SMITH
____William Andrew STROUP & Emma Ann RUSSELL
_____Arthur Norris STROUP & Anna Louise KISLING
______Pvt
_______Pvt - Haplogroup J2

Because the NPE could be anywhere along the line from our subject to Adam, this NPE has the potential for affecting many, if not all, of those who descend from Adam.

Our subject initially tested just 12 markers, which were enough to determine his haplogroup and his non-match with the other two paper descendants of Jacob. Fortunately, his haplotype is uncommon. Even at 12 markers, he has only three matches in the FTDNA database (in surnames HARRIS, BIDDLE, and LEVY).

Our subject has now ordered an upgrade to 37 markers, which will ultimately improve his ability to identify his ancestor. You may wonder if having an NPE doesn't doom one to never knowing the origin of their patrilineal line. The answer is, not necessarily. Luck is involved here, but we're already lucky in that even at 12 markers, this haplotype is uncommon. What is likely is that it may take years to solve the riddle, mainly in waiting for the just the right people to be tested and appear in either the FTDNA or Ysearch databases.

I have created a "node chart" for Jacob's descendants, with an explanation of the strategy for determining the location of an NPE.

As I emphasize there, any descendant of Adam has a stake in the outcome of this determination, so I strongly recommend that as many of you as possible join the project and become tested, to at least 12 markers. Twelve markers is enough to determine whether you do or do not share this NPE in your lineage.
