DNA testing

Starting in 2019, I have been doing extensive DNA testing of many branches of my family tree and my wife's family tree. I am testing with Ancestry, to maximise the number of real people we can connect to, and real lines we can prove.

So far, DNA testing has strongly confirmed, in many different lines, the accuracy of my family tree research. It clarified many existing lines, and proved many new lines. As a result, a large number of lines in the tree are now DNA proven.

• All DNA proven lines

• All DNA proven lines in my tree

• All DNA proven lines in my wife's tree

DNA testing for the Blennerhassett problem

The "Holy Grail" of my family tree has always been the Blennerhassett problem, the problem of figuring out how we descend from the Blennerhassett family.
After decades working with documents, it turned out that DNA was the breakthrough.
In 2020, DNA testing proved we are descended from the Blennerhassett Baronets branch.
See the Proof of our descent from Blennerhassett using documents plus DNA.
