Y-DNA
R1b, which originated in western Europe, is the most common Y-DNA haplogroup among Irish men, at a frequency of about 81.5%. I1 is the second most common with 6%, followed by I2b at 5%, R1a at 2.5%, and E1b1b at 2%. G2a is found in only about 1%. Also rare are I2a (1%) and J2 (1%).

Mitochondrial DNA (mtDNA):
about 38.5% of Irish people carry mtDNA haplogroup H (of whom 11% are in H1 and H3), 13% carry U (of whom 2% are in U2, 0.5% are in U3, 2.5% are in U4, and 6% are in U5), 12% carry T, 11% carry K, and 10% carry J. Several others are encountered at smaller frequencies: 4% in HV0 and V, 3% in I, 2.5% in W, 1.5% in X2, and 4.5% in other(s).

Red hair
According to The ALlele FREquency Database, 8.4% of the 226 Irish people studied carry at least one T allele in the R151C (rs1805007) gene where TT always causes red hair. That isn't the only red hair allele that Irish people sometimes carry. Between 4-6% of 23andMe's Irish customers carry the T red hair allele on the R160W (rs1805008, Arg160Trp) gene, while 4-6% of their Irish customers carry the C red hair allele on the D294H (i3002507) gene.

I'm R1b, but less commonly I'm in R-U152 >> L2 (seems to be linked with an Iron Age expansion of Alpine Celts, possibly with the La Tene expansion - my closest Y-STR result is with a guy from Switzerland). My final haplogroup so far has matches all over the place (England, Norway, Mexico, Italy) but not Ireland:

I have quite a bit of red hair on my Dad's side (which has trickled down to my son and my niece's daughter who have identical hair colour), which seems to have come in from my grandmother (a Ryan).

My mother's DNA Haplogroup is H (possibly H1). Her maternal grandparents were Mulvey and Gallager from Ireland.

I just added my mother's U4 (technically U4c1) mtDNA line to the project. Perhaps we should note haplogroups alongside surnames on the index?

It might be tricky as there is often some variation within families, especially ones that might have different origins. I know that one branch of the Barry family is under R-L2, alongside my own. I am also helping admin the Comerford DNA project and while all the estimated haplogroups from Y-STR are under R-U106 (so Germanic and consistent with Norman ancestry), the only person to do SNP tests (but not STR ones as far as I can tell) is under R-L21, which is one of the good markers for the Insular Celts (suggesting a NPE at some point after the family came to Ireland):

That said, it should be possible to include some Y haplogroup information, although it'd be best to leave the various surname projects to cover the nuances because there'd be a concern about people being upset if they aren't seen as, for example, "a true Murphy". Y DNA isn't family.

Hopefully you can see this Photo: https://www.geni.com/photo/view/6000000025916337033?photo_id=600000...

Here you can see the R-U106 mutation is about 2500 years old and R-P312 (of witch there are thousands of people with this SNP) mutation is about 4 to 5000 years old.

This a way before surnames and probably before our ancestors "moved" to Ireland.

That is why further testing is important to find the most resent ancestor.

Does not make sense. I'm Haplo E and belong to a line of Collins/ Orkneys/ small group of McDonalds with haplos dated 900 to 1100 years and linked to Orkney Scotland. But Ireland is also featured in our male paternal line. I think if we all can adjust haplo dates to conform to Judeo Christian timeline of 6022 years this will all make sense. Dont believe in Neanderthals since first man ADAM lived / was created in Africa. For all those hardcore scientists- who subscribe to a planet of millions of years why in Christ's name is the closest genetic match to mankind is the common garden variety pig?? Should it not be an ape/ monkey? Darwin was an idiot who married his cousin and is a close relative of Hitler. Why should i follow anything this idiot says? Bible takes precedence.

@Bill Barnes- my y-dna Haplogroup R-U106 not related to any others and negative to all current snp's possible to test ,approximately 3000 years separate from other R-U106 .
C Barry - some R-U106 moved 1400 bce from Central Europe ro Scandinavia so abit older than 2500 years.

Will - lot of Europeans have remnants of Neanderthal dna I have some Denisovian remnants.
Human development a lot older than any Abrahamic Religion timeline.
",adam " most likely Southern Africa more than 50 000 years ago
Humans closest DNA relatives are other primates not pigs .
