Blennerhassett of Co.Kerry
The "Blennerhassett problem"
Since 1985, the "Holy Grail" of my
family tree research has been the
Blennerhassett problem,
the problem of how we descend from the Blennerhassett family.
Since 1985, I had proof that we descend from
George Cashel (born 1807),
and evidence that George Cashel descends somehow
from the large and complex Blennerhassett family of Co.Kerry.
But through which line was unclear.
After many wrong turns, in 2020 I finally proved, through documents and confirming DNA,
that George Cashel descends from the Blennerhassett Baronets branch.
See
Proof of our descent from Blennerhassett.
We probably descend through a natural child in that branch.
But the details of how, and whose child, remain to be worked out.
Spelling
Normally
"Blennerhassett"
but sometimes
"Blennerhasset" (how the village is spelt).
And (as to be expected)
spelling of such a complex name varies widely,
especially before 1700.
I normalise the surname spelling in most places to "Blennerhassett".
Blennerhasset village, Cumberland
The family takes its name from the village of
Blennerhasset
(thus spelt now),
Cumbria
(formerly
Cumberland),
N England.
Blennerhassetts are found living at Blennerhasset
in the 1270s.
See
[Graham, 1932, p.49].
But later they are not found at Blennerhasset but rather
elsewhere around Cumberland.
(Obviously I am normalising the spelling to the modern spelling for surname and village.)

Myths and legends
Bill Jehan has a page of
Myths and legends
about the Blennerhassett family.
- There is a legend that the name came from a Blenner
marrying a Hassett.
- [Kelly and others, 1989, p.31]
has a story that Blennerhassett descends from Blenner.
- There is a legend that the name derives
from Blenheim.
- All these stories are false.
From
p.405
of
vol.1
of
Recollections of the life of John O'Keeffe
(1826).
This story is nonsense.
William Day Blennerhassett
in 1934 also has a version of this story,
along with other "oral tradition" fictions.
