humphrysfamilytree.com/challenge.html
A problem in late 18th - early 19th century Irish genealogy,
both Catholic and Protestant, probably in Co.Kerry.
Open genealogy competition launched May 2008,
to tackle genealogy problem unsolved since 1985.
Keywords - "Hard problems in genealogy",
"Unsolved problems in genealogy",
"Genealogy competitions".
There is one epic problem in all of my family trees
- the Blennerhassett problem.
For
years
I have been searching for the link of the Cashel family
with the Blennerhassett family.
I have gathered circumstantial evidence, but have yet to prove the link.
So I have decided to throw this open to the world
as
The Blennerhassett Challenge.
I invite anybody
who wants to tackle
a hard problem in genealogy to have a go at this.
This competition is open to both
amateur and professional genealogists.
I offer a
Reward of € 2,000
for the first person to solve this problem.
If you are a professional genealogist, I also offer
9 million views of your ad
by family tree enthusiasts for free, for five years. Details below.
years
so far
I have spent trying to
extract the Blennerhassett descent
implied
in the notes of my grand-aunt above,
and the Blennerhassett descent remains unproven.
Rewards
- 1st prize:
I offer a
Reward of € 2,000
for the first person who solves this problem
(i.e. finding the link of the Cashel family
with the Blennerhassett family).
I will pay by cheque
or by PayPal
or any other way you prefer.
- Kudos and publicity:
I plan to get some publicity for this.
I have already had considerable
media coverage
of my genealogy work
(in
Nature, The Atlantic Monthly,
The Wall Street Journal,
The Washington Post, Newsweek, Forbes,
Wired,
The Boston Globe,
USA Today
and
The Irish Times,
and on
National Public Radio, CBS News, ABC News, MSNBC, Fox News, CTV
and the
Australian Broadcasting Corporation).
I am confident that I can get the Blennerhassett Challenge
covered by the media also.
Amateur and professional genealogists alike,
this is a chance to
demonstrate your prowess

OK, now you are hopefully interested,
here is a description of the problem.
It is a problem in late 18th - early 19th century Irish genealogy, both Catholic and Protestant,
probably in Co.Kerry.
Summary:
- Our family descend from
George Cashel
(George Blennerhassett Cashel, born about 1807, Co.Kerry, Catholic).
- George Cashel's mother was said to be
Letitia Blennerhassett,
of the prominent Protestant Co.Kerry family of Blennerhassett.
She was said to be
disinherited for running away with a Catholic,
Edward Cashel.
"Her family disowned her but the Cashels all thought it very romantic."
Note that while George Cashel's name is certain,
his parents' names should be regarded as not certain.
-
The Blennerhassetts have a fantastic family tree,
including a Royal Descent,
which is why I am so interested in finding out if our Cashels
descend from them.
- When George Cashel joined the County Constabulary
(which later became the RIC)
in 1828
he was recommended by "A. Blennerhassett, J.P.".
This must be a relation of his,
and must be one of
these 3 Arthur Blennerhassetts,
all of whom are related to each other.
- The challenge is to find the link of the Cashel family with the Blennerhassett family.
That is, what is the exact relationship of George Cashel
to those 3 Arthur Blennerhassetts?

Unfortunately, he neglected to write down exactly why he was called Blennerhassett,
thus leaving it as a challenge for his descendants.

This brief note
in the BLENNERHASSETT entry in
[Burkes Irish, 1976]
by Brian Fitzelle
first made me realise in 1985
that my Blennerhassett line might connect to the World family tree.
