About us
Goals: This project encourages all participants to upgrade to Y-700 testing. Participants should be drawn from any of the following categories:
1) anyone who is R-L20+, regardless of country
2) anyone who has a R-M269+ Swiss patriline, especially from the cantons of Luzern, Zug, Uri, Schwyz, Obwalden, or Niwalden,
3) the Petermann family of Root, Switzerland, and
4) anyone who matches my brother or myself within 4 steps at 37 markers, or 1 step at 25 markers.

This project encourages participants to test in pairs: two brothers, a father and son, an uncle and nephew, or two first cousins. By so doing, this enables the component SNPs that have appeared within a family’s line of descent to become public.
Imagine how many lines of patrilineal descent have appeared since the advent of BY506, or of BY3595. Every time a patrilineal ancestor had two or more sons, who then went on to have their own families, a new subclade was potentially created. The genetic identity of these will remain obscure until descendants participate in Y-700 testing. Although the names and other details of most such ancestors from before about 1500 AD are lost to the winds of time, the existence, timing, and descendant surnames of these ancestors can be revealed through Y-700 testing.
My hope is that we can establish an accurate descendant list, showing just how the BY3595+ patrilines are related to each other. It will be interesting to see just how many of these are Swiss.
By getting a lot more Y-700 results for the clades nested under L20, the dates and 95% probability range for Family Tree DNA’s Discover application will tighten.
If you are R1b or R-M269, but don’t know if you are R-L20, you can test for that SNP individually. One could start with the R1b -M343 & M269 Backbone SNP pack and if L2+, you can then order the R1b -L2 Backbone test. By the time you have paid for both backbone tests, you will have invested nearly half as much as the cost of the Y-700 test. The best option would be to just go straight to the Y-700 test.
The real focus of this project will be R-BY3595 and subclades. How likely is a R-M269+ participant to be R-BY3595? Consider this, as of 2022, there have been 82,607 R-M269+ results.
8,206 (9.9%) of the R-M269 are R-U152+.
871 (10.6%) of the R-U152 are R-L20+.
81 (9.3%) of the R-L20 (81) are R-BY5690+.
Thus, there is about a tenth of 1% chance that an R-M269+ man will also be R-BY5690+. Only three of the 81 R-BY5690 participants are R-BY3595. That is based on current, known results. My conjecture is that there are probably a lot more R-BY3595+ men among those who have only tested to R-L20 or R-M269. But we won’t know just how widespread this is until they upgrade.
