Neil,
I met Lara a couple of years ago at Genetic Genealogy Ireland a couple of years ago? - she was very approachable.
And I ticktacked with her thereafter by email, initially to find out when her thesis might be 'unembargoed'.
She was not aware then that the embargo was going to be extended further ?.
The first embargo was clearly in relation to the publication in Nature about the Newgrange findings.
It is now embargoed to at least May 2023. And she is now probably unwilling to discuss any aspects of it.
Unfortunately after I let her know that her thesis was available elsewhere on the web, or perhaps after it was decided to extend the embargo, she has not replied to subsequent emails.
I think Nigel has also sent her an email that also remains unanswered.
I will try again.
John.
Did the project try approaching Lara Cassidy directly? The embargo period is the choice of the thesis author. In our collections policy that can embargo up to 5 years, after which time the thesis
is published on the institutional repository for all to see. Usually thesis authors put an embargo on their work in order to preserve the data for later publication, and publication can take a number of years to bring to market. However she might be happy
to discuss the sample with you.

BTW John, did you see the response I received from FTDNA in regard to VK202 (quoted below). It¡¯s interesting that there was no call on A151, but a call on A152 ¨C this perhaps indicates the order
of the 2 snips in the A151 snip block and A152 possibly formed first, with no calls to any downstream snips, or matches to any modern A151 snips. As such, it is possibly indicative of another A152 branch existing in eastern Scotland, which has not yet been
discovered in modern DNA ¨C or else has died off.

Best,

VK202 was placed at R-A151 based on his positive result for A152 (A151 has no coverage). He has no positive reads for anything currently down of R-A151. Negatives are very tricky to determine unless a sample is sequenced to a higher depth
(which VK202 was not).?
Private SNPs in samples like these are not able to be reliably obtained, again depth is going to be an issue here. VK202 also does not have any positive reads for any R-A151+ modern samples. R-A151 is as far as this sample can be placed at this time
?
in regards to STR calling - unfortunately this too is simply not feasible/possible
?
In regards to the actual sample itself, they would need to reach out to the authors of the paper. We have no affiliation with them or the sample. We merely analyzed the data

I had no luck finding an ENA number for the late Iron Age Claristown inhumation CT14 included in Lara Cassidy's thesis. It may have been embargoed like her thesis
?.
I don't recall looking for the other ENA numbers - I need to check my records.
