Proof of our descent from Blennerhassett
DNA testing - Blennerhassett problem
See Proof of our descent from Blennerhassett for the proof that we descend from the Blennerhassett Baronets branch. That we descend from this branch is proven, but the exact descent is unproven. The most likely theory is that the mother of George Blennerhassett Cashel (born 1807) is a daughter of Sir Rowland Blennerhassett, 1st Baronet (born 1740 or 1741) and his wife Millicent Agnes Yielding (born 1742). No other theory really explains the DNA evidence.
The story in our family is that George Cashel's mother was "Letitia". But the only known daughter of the 1st Baronet is Melisent Blennerhassett, baptised 1768. She may be George Cashel's mother and "Letitia" is an error (she is his aunt).
It remains to prove this from paper, to confirm from paper records what the DNA says must exist.

Me at New Ballyseedy in 1985, at the start of the life-long hunt for Blennerhassett.
The mother of George Cashel is not that far back.
She would be Ahnentafel number 89 (if I am number 1).
There are 64 people in her generation, numbered 64 to 127.
It may turn out that there is no Letitia Blennerhassett, and our ancestor is actually Melisent Blennerhassett.
John writes a joke letter to the Financial Times in 2008.
"How the Emerald Isle was turned blue" (and here), Financial Times, 22/23 Mar 2008.
"During his years in Japan (1891-1904), Lafcadio Hearn corresponded with a scholarly neighbour of his back in Ireland, one Letitia Blennerhassett. Though largely forgotten today, she was in her time a formidable scholar of the Irish language, collecting and translating a great deal of folk tales that would otherwise have been forgotten."
This letter was published, but the data is entirely made up.
