SENNETT SINNOTT SYNNOTT - cheaper YDNA 12 marker testing now useful

[corinne]

Any S-NN-Ts (particularly with Welsh or Irish origins) interested in DNA but put off by the cost of testing?

Having established that the genetic signature for S-NN-T's of Anglo-norman Co Wexford descent is a relatively rare E haplogroup, and that there are five different mutations among project participants in the first 12 markers, it is now useful to offer a 12 marker Y-DNA test as a preliminary screening tool.  This test is available through a join request to the Sennett/Sinnott project at familytreeDNA.com at a cost of $59USD (compared to the $149 cost for the 37 marker test).

Please encourage any of your male friends/family who have an unbroken male line connection to this surname to test.   We have some exciting results confirming common ancestors back as far as the 15th century now, but the more people in the project the easier it will be to fill in the gaps of the genetic tree and link your S-NN-T family back further.

(NOTE:  the recommendation for a 12 marker Y-DNA test is only for this particular group of surnames  - Sennett, Sinnott, Sinnett, Synnott and variants - and this surname project.  In most other surnames you need at least 37 markers to provide useful results - if in doubt, check with the surname project administrator)

Update on DNA testing for the Sennett, Sinnott, Synnott, Sinnett DNA project:   we are now largely using BigY testing as this is enabling us to predict date of common ancestor much more closely and to also build the genetic tree for people of this surname with 12th century Irish origin and especially those who have an E haplogroup (downstream of E-M35).  BigY is expensive, so the project is able to provide subsidies for testing if required.  We prefer that people join the project with a minimum of a Y37 test, and then depending on results, we can offer funding for upgrading some tests to BigY.   If even the cost of the Y37 is a deal breaker, there are a few initial Y37 test kits that can be made available, particularly if your family is not already represented in the project.   You can contact the surname project through the surname search link from the Guild of One Name Studies website.
