Hingerty YDNA Project- January 2023 report

Background:

We currently have nine Hingerty BigY700 testers representing the four exisiting Hingerty lines with living Hingerty males.

We have the results of eight of the tests, the most recent (BH, USA) becoming available this month (January 2023).

The ninth test (SH, Australia) was only taken and posted to the lab in Texas in late December. We will have those results in a few month's time.

We are using a combination of:

* Genealogical data

* STR data from YDNA testing (111 Markers)

* SNP data from YDNA testing (BigY700)

 to answer our two research questions Are all Hingertys related?  How are they related?

Thank you to our "Hingerty Heroes" JH, PH, MJH, SH, BH, MH, WH, DH and RH for taking the YDNA tests and allowing our research to progress.

What the results have revealed to date:

All Hingertys are related:

STR Evidence:

All Hingerty testers match at the STR 111 Marker level indicating that they all share a common male ancestor within the genealogical timeframe. 

SNP Evidence:

All Hingerty testers to date share (are positive for) the SNP R-FTB79857 indicating that the man in whom this variation formed is a shared direct ancestor for all four existing Hingerty lines.

SNP dating places the birth date of this man "Father Hingerty" at a mean of 1713. This date will shift around as more test data becomes available. It is the availability of this dating that makes the BigY test very suitable for assisting us with our research questions.

How are Hingertys related?

SNP Evidence:

All Hingerty testers to date are positive for the SNP R-FTB79857. 

(Note: the SNP names do not in themselves signify anything- what is important to note is who else shares/is positive for that SNP)

Three of the Australian testers (JH, PH, MJH) are positive for the SNP R-FTB81293 dated to about 1901.

Two of the USA testers (MH, WH) are positive for the SNP R-FTB79413 dated to about 1909.

In order to have a SNP named and dated you need at least two testers positive for that SNP with all other testers being negative for that SNP.

 We had hoped that by testing BH we might identify a SNP that formed in Alfred 1804 or William 1765 which would have firmed up the dating for "Father Hingerty". 

Unfortunately, in the words of Mick Jagger "You can't always get what you want" and the longed for SNP did not emerge. 

SNP mutations do not occur at every generation, they are random events and occur, on average, about every 83 years. 

From "Father Hingerty" at 1713 to William 1765 is 42 years and from "Father Hingerty" to Alfred 1804 is 91 years. So we are working at the outer reaches of probability for a SNP mutation to occur. 

With the data we have at the moment, it seems that there were no SNP mutations formed at the conception of William or Alfred since if there had been a mutation at either of these men they would be shared by all three USA testers and would have been reported in the results.

Hopefully, we will have more success with the results for (Australian) SH in identifying a SNP for John 1813 or his father John given that the timeline from them to "Father Hingerty" is longer and thus there is more potential for a SNP mutation to occur. 

STR Evidence:

There are very few STR variations between the various Hingerty testers indicating a relatively close relationship between them all- 'relatively close' meaning within the last 300 years or so.

It is interesting to note therefore that the three USA testers (MH, WH, BH) all share an STR variation at DYS391. They have 11 repeats at this marker while all other Hingerty testers have 10 repeats.

This indicates that these three USA testers are more closely related to each other than any of the other Hingerty testers.i.e it confirms the genealogical data.

Where to Next?

We await results for SH which are a few months away.

We need to now focus our attention on the Stafford and Ireland lines. 

As stated previously, you need two testers to both be positive for a SNP and all others to be negative, for a new SNP to be named and dated. 

To achieve this state of affairs you need two men who are closely related to test. 

This has yet to be achieved on the Irish and Stafford lines as there are to date only one tester on each of these lines. Our research cannot progress without these additional testers.

Further testers on these two lines will assist us to:

- research the relationship between Patrick and Denis- were they brothers?

- assist us to identify a timeline to the shared ancestor for the Stafford and Irish lines

- firm up the date for "Father Hingerty"

This would move our Hingerty research forward tremendously.

Of great interest would also be results for testers from surnames such as Ingerton and Hingerton that appear to be variations of a shared surname history. This would also move us forward in identifying a date for "Father Hingerty" and a better understanding of the relationships between the various surnames associated with Hingerty in the north Tipperary area in the 1700s and 1800s.
