67 markers of 453266 are now in, the remaining panels are pending. Earliest known paternal ancestor Denis Mahony, 1788 - 1872, of Bredagh, Drimoleague. This family had members named Cain. The match with the least genetic distance (62/67) has terminal SNP R-L21 and has an ancestor named Denis Mahony, probably kit #117777. The next match (61/67) is kit #123804, earliest ancestor John Mahony, Co. Cork, c. 1815. These matches are rather distant. But there is a perfect 37/37 match to kit #428112, ancestor Denis Mahony b1850 circa Drinagh, West Cork. Definitely our neck of the woods!

Sean, I see you attached John to the tree on Family Search! Well you solved a mystery. In the 1901 census there was a 14 year old John Mahony staying at the house of Rickard and Kate Ann Donovan in Drimoleague. He is marked as a "lodger." Now I know he was Kate Ann's younger brother.

Finbar, Would you please check our Big Y results for kit # 298068? Isn't your name listed with the RA 1338 marker? (We need to find a simple tutorial so we can learn to decipher the genetic data . regarding our closest matches. Do you recommend any particular one?) Every time a change is made or 'genetic cousins' are added . we won't have to bother you each time. Hugs to Fidelma for sharing you with the O'Mahony Clan.

Hello Madelline. As I mentioned on our FB Messenger communication R-A1338 and CTS4466 parted company a long, long time ago. The FAQ on the FTDNA site is excellent, Roberta Estes, Dr. Maurice Glesson, and Debbie Cruwys Kenneth have excellent blogs and you cannot do better than check the work of Nigel McCarthy on all aspect of the DNA of the families in Munster, see in particular his family tree of R-L21 and CTS4466. Just Google them and you will see that they are a treasure trove. A simple way of checking the relationship on the phylogenetic tree is to click on the haplotree on your personal page, the current terminal SNP will be highlighted in green, then enter the SNP you want to compare it with.... by tracing up or down the line on the tree to your own you can get an idea how remote the branching occured. Maurice Gleeson also posts the excellent presentations made at the BTOP Conferences at the RDS and elsewhere and therese will give up to date work on

We are researching information on > Cornelius O' Mahony < Born: 1840 in Macroom, Cork, Ireland & Died: Melbourne, Australia. He was a teacher. We are looking for name of his parents / siblings / wife & children. If anyone knows of family, please let us know. Thank you, Happy Ancestoring!

Pam, We are continuing the "Marney" search . which we found on one of the documents of our Grandfather's death certificate. It may have been spelled "Marny" & used as his middle name . after the surname was changed to "Willard". We were told, as children that the "M" was for "Michael". (These surname changes are like searching for a needle in a field of shamrock.) Hope you will continue your search. We are waiting for more of the gentlemen to test for RA 1338 SNP. Seems we are out on a lone branch of the tree. Again, we "hurry up & wait."

Finbar, How do we contact those we want to reach if they turn off all below Y37 ? After a couple of years we still have only two @ Y67. Also, who do we contact to find out who submitted the FTDNA test kit number? The removal of name & 'most distant ancestor' (mda), must be from the recent EU privacy law. (Just wondering about that, since realizing that many Irish parents used the Irish traditional 'naming' after Grand-fathers, Uncles, etc.) It is amazing how many questions come to mine!

Yes Madeline. The GDPR regulations require us to ensure that emails are only available on the individual's personal page. Genealogical questions should be directed to the Society Facebook page and FamilyFinder queries are beyond the scope of thhe yDNA project. In thhe past two days I received a mildly irate email from the admin of a kit. The owner was an O Mahony but did not want to participate in "research" The owners of the kits can opt out of notifications below any level (37, 25, 12) and can also ensure that even the administrator does not have Full Access. Kit numbers shown in black rather than blue on the spreadsheet are uncontactable but can only be removed/deleted by the kit holder.

Thank you, Finbarr, I have a few contacts from Gene's Y- results listed, and Greg (Au.) was kind to see that we were able to contact one another. (I will let you know if the results prove favorable. ) Sorry, I have taken so long to answer .... Gene's wife, Dorothy, took a turn for the worse & passed away since I last contacted you. Gene (age 88) drove up from Houston, Tx. to see us, this week. He was pleased with the Y-discoveries and says "Hello" to you .. sending his best wishes. Thank you, for your kindness & guidance along the way.

I recently had my brother's test upgraded to 67 markers. Our surname is Murphy, but all our matches say Mahoney. I am trying to figure out if this is a NPE or a variation on the Gaelic name O'Mahoney. Also, will my brother's results get added to your spreadsheet? How does anyone get added to your results?

have you done any SNP testing ?
Finbar O Mahony
February 13, 2019 @ 5:21pm
Hello Erin. When you say "all or matches are O Mahonys" can you say how many matches named O Mahony your brother has please? What haplogroup is he? The early Murphy (O Murcu) is found the East coast but spread throughout the South. It has a distinctly different haploroup from the one associated with the main body of the O Mahonys. We have two exceptions named O Mahony/Mahoney or a variant who share an early common ancestor named Murphy. Perhaps the two exceptions could add the Murphy project to the list of "project joins"? I am not at liberty to suggest that to them. If you let me know the halpogroup for your brother we can see what would be the better course of action. Without that information it would be premature to talk about which family was the source of a possible NPE, adoption, fostering leading to a name change or the child of a first marriage taking the name of his stepfather out of gratitude, respect or as a requirement for inheritance.

My brother is L-226. I just upgraded his Y DNA to 111 markers and we have 2 matches at that level. Both a Michael Mahoney from County Cork, Ireland. At the 67 marker level, we have 9 Mahoney matches at a genetic distance of 5 or less. I have been told that halogroup L-226 is from Counties Tipperary, Clare, Limerick & Cork. Does this help?
Erin Garcia

We are already members of the Murphy project. I just checked and we seem to be the only L-226 in their database.

I'm part of the McMahon group. My brother Jerry McMahon and I have discovered that we appear to be part of a sub group of the O'Mahony's. Anxious to find out more about that. My kit # is 658950 and i'm in the R-M269 Haplogroup.

Hello, Robert, I have an e-mail address from my brother's YDNA test match. The person to submit the > Clarence B. Mahoney, J. < name with his earliest known ancestor > James Mahoney ( 1820 - 1846) Woodville, Mississippi, USA. The e-mail of the person submitting the names & dates > mahon329@gmail.com < My brother, Eugene (Gene) Powell Willard shows he is 4 step at 59.12%. In other words, we have a genetic match, as well. Also, Frances Van Lier, is friends on my Facebook page & she was a Mahoney (who had McMahon's in her family. She lives in New Zealand. I believe Greg Mahoney knows her. My Facebook page is listed > Madelline Willard Copeland < You will find Frances is listed as "Friend'. (Our Grandfather's name was James.) Hope this helps to lend a bit of info.

Hi, Robert! My cousin, Patrick Mahoney, did a YDNA test, and he was R-M269, also. The odd thing was that there were more McCarthys then Mahoneys. Only one Mahoney (I think a John Mahoney) was the only one with a R-M269 match. As you may know, the R-M269 goes back to 25,000 years.

March 1, 2018 @ 9:23am
Hello, First of all, if you could be tolerant about my english because I'm french ! I recently received my Y-DNA 37. I found 2 matches at 37 markers, with a genetic distance of 4. One of them is Sean O'Mahony. For him, the comparison chart show me a percentage of similarity of 88.06%, at the 8th generation. I would understand what is the most important: markers, genetic distance, percentage ? To explain my target with this Y test: I'm looking for the father (unknowm) of my g-g-g-grand-father, born in 1816, in France. The matches I found are both irish ! Between this unknown father and me, there are actually 6 generation. If I have to select markers which match with me, is it better to research low genetic distance or high percentage ? In this kind of test, at what level a percentage become meaningful ? Thank you for any help, Loïc Mairesse

There were many Mahony/O'Mahonys Soldiers from Kerry and Cork living in France around 1790's. I would go up to 67 markers

Hello, Thanks for this track.Do you know any register or books about this migration ? About a 67 markers test, I first asked for a SNP package test, to show in what specific haplogroup I am.

Hi, O'Mahony Society members! I VERY recently learned that my 2 gr grandfather, Denis Mahony & 2 gr grandmother, Margaret Grimes were md. Feb. 7, 1839 in Schull East, Cork, IRE in the parish of Cork & Ross parish. Their 1st child, Jeremiah, was Christened May 3, 1840. Shortly after, they left Schull and all three settled in Auburn, Cayuga, NY abt. 1844 when my gr grandfather, Patrick, was born. I was surprised reviewing the church records that very few women were sponsors for marriage and baptism. About 98% of the sponsors were men. Also, my male Mahoney cousin did a Y-DNA test which seems to indicate that we were originally McCarthy clan on father to father DNA. Maybe our distant grandfather McCarthy was adopted to a Mahoney family OR we may have a naughty distant grandmother! I have not contacted the Y-DNA O'Mahony Society in regard to the McCarthy mystery if they know of the history. Thank you SO MUCH to contact me, and hope to hear from you soon. Regards, Diane in Baltimore, MD

October 15, 2018 @ 7:21pm
I recently took the Ancestry DNA test for comparison. It shows no connections to County Cork back to the 5th through 8th cousin (roughly equating to the 5th-8th grandfather). Is it possible my ancestors were already here in the US by that time? Earliest Mahoney in Maryland, US I have found was Timothy Mahoney, circa 1680. He would have been the 9th grandfather (IF he is an ancestor - not proven yet).
