DNA results Q-YP4004

The Stephens-Stevens DNA Project Group: Q-M242 has one individual claiming John Stevens (grandfather of Samuel) as their Most Distant Known Patrilineal Ancestor (MDKPA). They have done no SNP testing, but have 67 Y-STR tested. FTDNA predicts they fall under Q-L53. Plugging the STR results into the NevGen Haplogroup Predictor arrives at Q M346>YP4004 with 91.79% probability. Using the https://genetichomeland.com predictor shows Q-YP4004 documents where this clade was found in Prussia (now Poland), Crimea and Chechnya. As none of these locations are known to have early immigrants to New England, it is likely either the NevGen Haplogroup prediction of Q-YP4004 is in error, or possibly a Non-Paternal Event happened somewhere in the patrilineal ancestry of the DNA tester.

Further DNA testing needed

Testing of additional patrilineal descendants is needed. Any male who believes their patrilineal ancestry goes through John Stevens (and preferably through his son Samuel) is encouraged to contact MayflowerDNA1620@gmail.com
