My Healy DNA only goes back in Ireland 5400 years or so

 I ran my Y-DNA on http://www.familytreedna.com .  Yep, definitely a Healy.  See pic below.

My DNA was noticed noticed by a researcher named "bernie".  Bernie is very good at tracing ancient lines and interpreting dna results.  He had met take a "Big-Y" test to further refine my results.  Y-DNA offers you a father to son direct dna pass, m-dna does mom. Big Y fully maps out the chromosome sets so guys like Bernie can understand it further.

A lot of the DNA connections ( Y-Paternal as well as 'cousin' matches ) put me in line of the Kilgarvan Healy-Rae's.  Not exactly Healy-Rae since the Healy-Rae name wasn't  used until the 1940's by Jackie-Rae Healy, but up their ancestor chain.  Jackie Healy-Rae's father, Daniel, and my great-grandfather Dennis were brothers.  Ancestry says Jackie Healy-Rae and are are 1st Counsins 1x removed.  Michael Healy-Rae, is my 2nd cousin 1x removed.  See Michael Healy-Rae in action re DNA here - http://www.dailyedge.ie/michael-healy-rae-late-late-3294284-Mar2017/ .

According to Donal Healy's book "The Healy story: Oidhreacht mhuintir Ui Ealaithe" (  http://amzn.to/2mEbBEr  ) ( good luck getting a copy )the Kilgarvan Healy's are rumored to come from Donoughmore during the penal times after killing a tax collector.  Over the mountains (maybe they even used Healy pass), across the bay, and start farming in Kilgarvan.

Bernie's DNA research clarifies the klans and how long they've been there.  If you're interested in getting in  touch with Bernie ping me and I'll forward your email to him via the comments below.

Re my DNA I am I-PF6497+ which is apparently under the I-P37 subgroup and the I-M26 haplogroup.

On my big-Y I am YF07184IRL [IE-KY] (Kerry).  My http://www.gedmatch.com kit is A869398 .

Iinformation on the I-M26 tree at YFull (which they call I-L158): https://www.yfull.co/tree/I-L158/ .

Highlights from Bernie's notes. Fascinating stuff!

• According to Wikipedia, the Healy-Reas are Healys from Kilgarvan, Kerry. Several Kilgarvan Healys belong to the I-M26 paternal haplogroup and they are some of the closest matches to my Cullen family, with a common ancestor estimated at 1200 years ago according to Big Ys This mainly Irish branch is called I-Y15581 and includes families named Cullen, Carbery, Healy, Hurley/Murley, Crowley and one family named Felce/Felch/Phelps/Phillips that is English or Welsh, and also one man born in Iceland who believes his ancestor was an Irish slave according to the Iceland histories. Probably the Y-DNA ancestor of all these people arrived in Britain/Ireland sometime between 5,000 and 4,000 years ago, the next closest Y-DNA relative lives in Sardinia. So it's a very Irish branch, and maybe the Healy-Raes belong to it. https://www.yfull.com/tree/I-Z27396/
• Close big Y matches are Healy, Cullen, Crowley, and Felch. Estimated common ancestor 3800 years ago.
• Crowley and Felch families are related to two other Irish super-families: the Cullen/Knox/Carbery/Carberry/McCarbery/Donohue family and the Healy/Haley/Spain/O'Donoughue/Dwyer family. The Healy family is from Kerry and Cork.  The Cullen/Carbery group and the Healy group are quite closely related to each other..
• More distantly, all of these Irish/Welsh/English families are related to an anonymous man living in Sardinia, he was part of a scientific study and he is known by the code ERS256272. The common ancestor between the Irish families and the Sardinian man is calculated to have lived 5400 years ago. The Sardinian man and the Irish men are all PF6947+ and they also are positive for Z27396 and 8 additional SNPs.
• For many years people speculated that the I-M26 group in Ireland, Sardinia, France etc represented the "megalith builders" spreading their culture around the Atlantic parts of Europe. I thought this was very fanciful, and I thought it was equally likely that my I-M26 ancestors had been in Ireland even longer. But this match with the Sardinian man seems to show that our ancestors were not in Ireland 5400 years ago, instead they were in Sardinia, or more more likely somewhere like France or Spain. And our paternal ancestors seem to have arrived in Ireland over 4000 years ago. So it now seems certain that our particular branch of I-M26 was not among the earliest hunter gatherers to arrive in Britain and Ireland, but instead came later, and in fact could have been part of the people who built the megaliths.
