Blennerhassett of Co.Kerry
The "Blennerhassett problem"
Since 1985, the "Holy Grail" of my entire
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,
and evidence that George 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 we
descend 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 throughout to "Blennerhassett".
Blennerhasset village, Cumberland
The family takes its name from the village of
Blennerhasset
(thus spelt now),
Cumbria
(formerly
Cumberland),
N England.
The family took their name from this place
but they did not have lands there
(or at least, not since the 12th century).
Their lands
were elsewhere around Cumberland.

- Various myths have been believed about the name Blennerhassett:
- 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.
