DNA results I2a2a>>L623

Previous Y-DNA testing

The Family Tree DNA Dennison DNA Project currently does not separate the various Den(n)ison families. However, a private correspondence with the administrator of the project noted where several descendants of George Denison had taken the old Ancestry Y-STR DNA test. Plugging in the modal values from these tests into the NevGen Haplogroup Predictor gave a prediction of: I2a2a>M223>Z161>L623 with a 99.7% probability (however, having a fairly low fitness score due to lack of STR values).

Further needed testing

We need direct male-line descendants of this Denison family to WGS/NGS test to discover where this family falls in the Y-DNA tree.
