New Discoveries! Hingerty YDNA Update- July 2022

 

New Discoveries!
Hingerty YDNA Project Update
July 2022

Family Tree DNA (FTDNA) has recently introduced a new suite of tools (currently in BETA) to assist dating on their Big Y haplotree. 

Applying these new tools to the 5 Hingerty Big Y tests taken to date has greatly assisted in the dating of our Hingerty YDNA tree.

Australia:

Three of the Hingerty testers to date (JLH, PH, MH) are direct descendants of Thomas Joseph Hingerty born in Australia in 1868. 

Thomas was the youngest son of John Hingerty who was born in Tipperary about 1813 and emigrated to Australia in 1841. We have not been able to verify John's birth date or place, nor have we identified his parents with 100% certainty. This research is ongoing.

Testers JLH, PH and MH all share the same haplogroup R-FTB81293

However, we do not know if their shared mutation was formed in their most recent shared ancestor Thomas Joseph Hingerty OR his father John Hingerty.

Using the new Discover tools we are told the following:

Unfortunately the dating placing this man's birth from 1800 does not help us distinguish between Thomas Joseph (born 1868) or his father John (born about 1813).

Looking at the probability plot which accompanies the text gives us a few more clues....

If we plot John's 1813 birth and Thomas Joseph's 1868 birth dates on the graph- it is more likely that the mutation R-FTB81293 shared by testers JLH, PH and MH was formed in Thomas Joseph rather than John.

So, we are getting closer to being able to assign this mutation (and thus this branching point on the tree)  to John or Thomas Joseph, but we are not there yet.

If a direct descendant of Thomas' brother, John Alexander, took the Big Y test, we could be more certain if the mutation started with Thomas Joseph or his father John. 

(If the John Alexander tester shares the mutation then we know it started with John, if the John Alexander tester does not share the mutation then we know it began with Thomas and we would have a new branch formed by John Alexander.)

USA and UK and "Father Hingerty":

To date we have the Big Y results for 1 tester in the USA  (MH) and 1 in the UK (DH).

They share (along with the 3 Australian testers) the haplogroup R-FTB79857. In previous reports this mutation was dated from 80 to 900 years ago. The new Discovery tools have reduced this timeframe dramatically. The report now reads-

The gap has been reduced to 250 years (+ or - 100 years) with a 95% probability that the mutation was formed in a man born between 1700 and 1900. This is a very exciting development!

I have come to think of the man represented by mutation R-FTB79857 as "Father Hingerty"- the common male ancestor shared by all existing direct Hingerty lines alive in the world today. 

Identifying the timescale and the branching points from this "Father Hingerty" will help us answer the long asked question- "How are the Hingertys related?"

Recently another descendant of Otis Hingerty in the USA took a Big Y test (tester WH). His results are still being processed and we wait with baited breath for his results which, hopefully, will cause another branch to form representing the USA descendants of William Hingerty and separate the USA branch from the UK branch (represented by tester DH).

I sincerely thank WH for taking the Big Y test- his results will greatly assist our research.

We need another UK male Hingerty to take the Big Y test for us to compare with UK tester DH and refine the dating and the branching points for this line in the tree.

Ireland:

To date no Dublin Hingerty males have taken a Big Y DNA test, so no comment can be made as to where they fit into the Hingerty YDNA tree.

If 2 closely related Dublin Hingerty males took the Big Y test, their branch would be formed on the tree, we could see how this line relates to the lines in the UK, USA and Australia and dating could be undertaken.

Current YDNA TREE:

Following the reports produced by the new Discovery tools at FTDNA, our Hingerty YDNA tree now looks like this:

We are inching closer to being able to answer the two big Hingerty research questions:

Are all Hingerty's related?

How are they related?

If you have any questions, would like to contribute towards the cost of YDNA testing or if you are considering taking the Big Y test- PLEASE don't hesitate to contact me.
