The "Blennerhassett problem"

The "Holy Grail" of my family tree research has always been the Blennerhassett problem, the problem of how we connect through George Cashel (born 1807) to the Blennerhassett family.

In 2020, I finally proved that we connect to the Blennerhassett Baronets branch. See Proof of our descent from Blennerhassett. Some connection to that branch is now proved, but the details remain to be worked out.

Nothing is known about Cashel outside of George Cashel

On the Cashel side, almost nothing is known. Our ancestor George Cashel has no known Cashel relations. We are not even sure if it is a real surname, or a surname made up for a natural child.


The proper spelling of our family seems to be "Cashel" not "Cashell".


The Papers of Patricia Lavelle give a descent from Blennerhassett through George Cashel's mother "Letitia Blennerhassett".
DNA and other evidence proves George Cashel is likely the grandson of Sir Rowland Blennerhassett, 1st Baronet.
However the 1st Baronet has no daughter Letitia, and in fact no daughter that survived past infancy.
"Letitia" may be an error, and in fact George Cashel's father may be a Blennerhassett, son of the 1st Baronet, so the below would have to be totally re-written.
Until we prove that, we will stick with Pat's story that the Blennerhassett descent is through the mother:

The notes of Pat Lavelle show the mother of George Cashel as a Letitia Blennerhassett.


George Cashel's middle name

George Cashel is normally written with no middle name.
He is "George Cashel" or sometimes "George Cashell".
But he does appear during his life as "George Blennerhassett Cashel" and "George S. Cashel".
[PAT/13, no.6] also lists him as "George Edward Cashel", but this is long after his death.

Real Gaelic descents v. Imaginary Gaelic descents


Some fictional Gaelic genealogy about Cashel from Pat Lavelle in [PAT/4].
She refers to her grandfather Blennerhassett Cashel.
Pat was fascinated by old Gaelic Ireland, but ironically, she could not see that Blennerhassett, not Cashel, or O'Mara, or any other family, was the only line that would give her a real descent from old Gaelic Ireland.


There is another link to Irish nationalism: Rowland Ponsonby Blennerhassett, MP, the famous Home Rule MP elected in 1872.
According to my theory of our descent, Blennerhassett Cashel was his 2nd cousin.
Pat Lavelle was aware of Rowland Ponsonby Blennerhassett, MP, and talks about his famous victory for Home Rule in [PAT/12, p.14-15]. But she does not write down our link to him.
