Hingerty YDNA Project Report September 2023

What we know now that we didn't know before:

1. All Hingertys are related. We have now tested 11 Hingerty males who represent at least 2 male testers from each of the 4 existing Hingerty lines who have males alive today.

They all match each other on both STR and SNP testing. That is, they all share a common direct male ancestor.

2. The Time to Most Distant Common Ancestor (TMDCA) is currently estimated to be around 1717. This date may change as more testers are tested and more data becomes available.

3. Using this current date of 1717 as a ball park figure and estimating the number of generations needed to 'fill in the gaps' from the known most distant ancestors of each of the 4 lines, we can guesstimate that the Hingerty testers are about 7th or 8th cousins to each other.

4. Our Hingerty testers match (more distantly) Harrington males from Cork. This supports the hypothesis that we were all originally of the O'Hingerdell clan which occupied lands in the Cork townland of Kippaghingerghill prior to the winter of 1602/3.

5. Further, it supports the hypothesis that the surname Hingerty developed in north Tipperary after one or more O'Hingerdell males left the Great March of the O'Sullivans which passed through the area in January 1603.

6. The recent Y37 Marker testing (and match to our Hingerty males) of a Templederry Harrington male who has a family oral history of having arrived in the Templederry area with O'Sullivan in January 1603 further supports our Cork to Tipperary hypothesis.

7. Our YDNA tree now looks like this:

What we still don't know:

1. The details of our relationship to the Templederry Harrington who recently tested. We hope that this tester will upgrade to the higher level BigY700 test so that we can gain dating and more information about his relationship to our Hingerty testers.

2. Are we related to other Tipperary Harringtons? How are we related? Further candidates for testing will need to be identified and recruited.

3. Are we related to Ingerton and if so, how and when? An Ingerton male is testing at BigY700 level in the near future. We await his results with great interest.

4. If the Ingerton male is a match, his results may assist us to refine the dating for our MRCA (Most Recent Common Ancestor).

5. Are we related to Hingerton? Trees have been developed for Hingertons who were in Tipperary in the 1800s and contact has been made with potential testers. No success to date.

6. Were Patrick 1811 (ancestor of Stafford Hingerty line) and Denis 1809 (ancestor of Ireland Hingerty line) brothers? Our two recent testers, PH (Stafford) and SH (Ireland) caused branching points on the YDNA tree thereby creating Stafford and Ireland sub branches.

However, their results did not resolve the question of Patrick and Denis being brothers.

If DH on the Ireland line would test, we might be able to resolve this mystery. We live in hope that he will test.

Where to Next?

Our areas for attention in order to 'grow' the Hingerty YDNA tree are the two areas of "Block of Equivalents" marked in purple and red on the Block Tree.

Each of the mutations listed inside the blocks are potential branching points for the tree. To create a branching point we need some testers to test positive for one or some of these mutations (and all testers listed below the block have already tested positive for them...) and other/s to test negative (these will be new testers).

a) To break up the purple block and hopefully resolve if Patrick and Denis were brothers- testing of DH on the Ireland Hingerty line.

b) To break up the red block and gain more information re the relationship between Hingerty and Templederry Harrington: Upgrading Templederry Harrington tester to BigY700 level.

c) To break up the red block and gain more information re the relationship between Hingerty and Tipperary Harringtons: Identification and recruitment of more Tipperary Harringtons who had ancestors in the same areas in north Tipperary as Hingerty and Templederry Harrington families.

d) To break up the red block and gain more information re the relationship between Hingerty and Ingerton: await results from Ingerton test. (PI)

e) Continue efforts to recruit Hingerton tester/s.

f) Research and build trees for the surname Hennerty in Cork and Tipperary to work out if they could also be related.

We have come very far indeed and with more research and more testing we might be able to explore areas of our family history previously unknown to us.

Thank you to all the Hingerty, Harrington and Ingerton testers.

Without your results we would still be back wondering if we were related and where our surnames came from before we arrived in Tipperary.......
