You can find the project at the Family Tree DNA project site.We have four participants, and a fifth who has shared his results with me privately.I am in the process of updating the website to include all five partipants' results, under the name of their earliest known ancestor.
I am insanely busy, so it make take me a while to upload all the results, etc., so if you decide to participate, or if you already have results through another project and would like me to send you the results I have to compare to yours, please let me know.
None of our participants is related as yet, so all six represent six different Shaffer or Sheaffer, etc., lines.One participant has roots in Fayette County, PA; another in Pa to Madison County, Illinois.Another is descended from the numerous and rather well-known Pennsylvania Shaffer family whose descendants ended up in Butler County, Ohio and neighboring Indiana counties.Another has traced his family from Pennsylvania to Germany.Another did not provide any ancestor information.
I hope you will seriously consider participating.The more we have, the more connections we will begin to make.In one case already, descendants were in the same Illinois county.It was thought they were related and the DNA showed that it was not the case.Now, we won't waste time researching a line that wasn't related.
Thank you so much for your interest.Please email me with any more questions or concerns.
