Fitzpatrick DNA Project Update – January 2019

 

1.    General News

 

We are enjoying good project growth with project numbers recently breaking through the 400 mark. So, a big welcome to new Fitzpatrick members as well as several folks who don’t have the surname Fitzpatrick, but who are critical to helping us understand some of our older genetic roots.

 

We have also seen increased levels of testing in the past few months. Mostly importantly there has been a greater uptake of NGS (Next Generation Sequencing) tests. Our thanks go to those who have made sizeable financial donations to the project in order to facilitate much of this testing, namely: Tim Fitzpatrick, Joe FitzGerald, Mike Fitzpatrick and the Fitzpatrick Clan Society.

 

2.    Summary of Recent Results

 

FGC5494…A1506

As well as trying to learn more about individual genealogies, a big focus has been trying to understand the relationships between men who share DYS390=21 and YCAII= 22-23. This group has benefited from several new members and new results. 

 

At this stage it appears likely the FitzGerald and Fitzpatrick branches will all defined under FGC5494…A1506>A1496>A1488. And the addition of a Brennan, who has a BigY, to the project has enabled us to understand the Brannan branch is probably defined under FGC5494…A1506>BY140757. All that is really missing in our quest to unravel the complexity of the FitzGerald-Fitzpatrick-Brannan-Dalton relationship is a Dalton BigY, which we are working on.

 

Z255>Z16434

Z255…BY2849 Fitzpatricks continue to surprise. We now understand there are four discreet genetic branches that are also distinct geographically: (i) BY17792 (Newry, Co. Down); (ii) BY2893 (Iveagh, Co. Down); (iii) BY2894* (Co. Kildare); and, (iv) BY52612 (Co. Louth). BigY tests on Co.Louth Fitzpatricks, in particular, have enabled this sub-group to make connections that were never likely to have been made any other way.

 

FGC11134…CTS4466

We now have our first NGS test for a CTS4466 member who traces to Co. Kerry. They are CTS4466…A923. It’s too early to know if A923 will define all of this large group, but it is likely that many CTS4466 Fitzpatricks on the project will be A923 and have roots in Co. Kerry or Co. Cork. Members of this group please email us if you’d like to test further and we’ll see what funds can be made available.

 

Although there have been no new NGS results in the large FGC11134…BY9002 group we are now also calling for members of this group who would like to take an NGS test.

 

3.    Major Results in the Pipeline

 

In FGC5494 we await the important BigY for a Costigan, which will most likely enable us to calibrate the age of mutations in the FGC5494 group against what we understand about Fitzpatrick-Costigan genealogy. Another family member of Tim’s awaits their BigY, which will enable the aging of his branch with more precision. Recently, another Fitzpatrick with good genealogical records has decided to take a BigY; we hope this will allow us to understand Fitzpatrick connections as well as afford greater confidence in our estimate of the age of A1488. Finally, we have a new non-Fitzpatrick member who is taking the BigY. He traces to North East Italy and his relationship with Fitzpatricks is from before the time of surnames; we think his results will shed considerable light on the origins of FGC5494 Fitzpatricks ca. 500-1000 AD.

 

In Z255 we are waiting for an Ireland surname BigY that should result in some further branching of the Ireland tree and a more precise estimate of the age of BY17850.

 

There are also a couple of BigYs coming for project members who are on the study because of autosomal matches to Fitzpatricks.  We wish them luck with those.

 

4.    Admin Matters

 

For those with folk on the Y-DNA part of the project, if you haven’t done so already you might like to consider adding information about your MDA (name, DOB, location).

 

And for those who may have missed it, if you want to see your Y-DNA results on pubic display (https://www.familytreedna.com/public/fitzpatrick?iframe=yresults), just email us.

 

5.    Autosomal Analysis

 

We have mentioned previously that project administrators are able to conduct a slightly deeper analyses your autosomal results than you can as an individual. If you would like us to look at your autosomal data in this way feel free to ask. 

 

 

Best Regards
