A totally of 7 Y-DNA test with a varying number of markers has been tested to date. Not all are listed here as one person declined to join the surname project and two tests were done by Ancestry.com when they offered Y-DNA tests. However, the administrator is in possession of test reports from all tests.
The following marker adjustments were done before comparison of the results.
Y-GATA-H4 Ancestry value - 1 = FTDNA value
DYS441 Ancestry value - 1 = FTDNA value
DYS442 Ancestry value - 5 = FTDNA value
GATA-A10 Ancestry value - 2 = FTDNA value
Analysis of results
Since these tests are done with varying number of markers, the only commonality is at the 12 marker level. At this level, all tested individuals are believed to be related within about 7 generations based upon this: https://www.familytreedna.com/tr_Y12M.pdf
The most notable results are from kit 70433. While this particular person has declined to officially be a member of this project, they did provide both their test report and information on their ancestors. They are a direct descendant of Capt Henry Shepler (01 Aug 1737 - d 18 Oct 1781) ) of Berks County, PA.
The conclusion from this is that the descendants of Henry Shepler of Berks County, PA are indeed related, within a genealogical time frame to the Shepler family of Westmoreland County, PA who, before the Revolutionary War, lived in the area near Winchester, VA.
The most significant need for this research project now is to find another male Shepler descendant of Capt Henry Shepler of Berks County, PA who might be interested in doing a 111 marker Y-DNA test. This test will provide a much more concise estimate of when the most recent common ancestor lived and this will thus make normal genealogical searching for records a little easier.
