DNA testing

  


DNA testing for the Blennerhassett problem

The "Holy Grail" of my family tree was the Blennerhassett problem, the problem of figuring out how the Cashel family (our family) descends from the Blennerhassett family.

After years of gathering paper evidence, I turned to DNA.
In 2020, DNA finally proved we are descended from the Blennerhassett Baronets branch.


  


Other DNA testing

I have looked at DNA in other (non-Blennerhassett) branches of my family tree, and in my wife's family tree.

This clarified many existing lines and proved many new lines. As a result, a large number of lines in the tree are now DNA proven.
