DNA tests of the dead

To help solve the Blennerhassett problem, we are doing extensive DNA tests of the living.

How can we do DNA tests of the dead? Two ways:

1. Digging up the dead from graves and DNA testing them.
2. DNA tests of artefacts, notably human cells left by licking postage stamps.

The first is impossibly difficult logistically, legally and ethically.
The second is new, experimental and expensive. But maybe possible for our purposes.

List of available DNA of the dead

Here is a list of (some of) the possible available DNA of the dead that could help solve the Blennerhassett problem.
As said above, the postage stamps are the only really practical source.
But we will list the graves just to see what exists.

Blennerhassett side (needs more work)

Generation	Person	What survives	Image	Notes
1st Baronet	1st Baronet	Graveyard		Buried at Dromavally, near Killorglin. Maybe Blennerhassett vault could be identified.
The sons	Rowland Blennerhassett of Kells	Graveyard		Almost certainly buried at Dromavally, near Killorglin. Since his son was buried there.
1	Son of Rowland Blennerhassett of Kells	Graveyard		Rowland Blennerhassett junior is buried at Dromavally.

Blennerhassett side

Generation	Person	What survives	Image	Notes
The sons	Arthur Blennerhassett	Grave		Inscription: "The Family Burying Place of the Blennerhassetts of Blennerville". So there are clearly more than Arthur here.
1	Daughter of Arthur Blennerhassett	Grave		Theodora Blennerhassett is buried with her father Arthur.
2	4th Baronet	Grave
2	Rowland Ponsonby Blennerhassett	Grave
2	4th Baronet	Stamp		Stamp from him in 1870-1909 almost certainly exists in Cambridge papers.
3	5th Baronet	Stamp		Postcard dated 1890.
3	Major Richard Chute	Stamp		Postcard dated 1932. SL/B/26(1) in Chute papers
4	(Irrelevant)	Living DNA		We got DNA from multiple living people in generation 4 for the Letitia theory. But those are now irrelevant.
5	Multiple people	Living DNA		We got DNA from multiple living people in generation 5 for the Baronets theory. And we can still get more samples.

Cashel side (needs more work)

Generation	Person	What survives	Image	Notes
1	George Cashel	Graveyard only		Grave not known. Would have to exhume and test whole graveyard until get match to our family.

Cashel side

Generation	Person	What survives	Image	Notes
2	Blennerhassett Cashel	Grave
3	Children of Blennerhassett Cashel	Graves		Lots of known graves of children of Blennerhassett Cashel (and their 1st cousins). But no point. If going to exhume anyone, will exhume Blennerhassett Cashel.
3	Agnes Cashel	Stamp		Postcard dated 1950.
4	Steen O'Mara Patricia O'Mara Eithne O'Mara	Stamp		Postcards for all of these. Various dates.
4	Multiple people	Living DNA		We got DNA from all living people in this generation. No more exist.
5	Multiple people	Living DNA		We got DNA from multiple living people in this generation. And we can still get more samples.
