Hi. My name is Lisa and I manage my cousin Darrell O'Sullivan's DNA. We have done some YDNA testing and all close matches come back AGEE.... I am hoping maybe we can get more answers. Can someone please look and see if they see something we are missing?? his GEDmatch is A072809, his brother Thomas O'Sullivan is A969285, his brother Kelly O'Sullivan is A49153 my GEDmatch is A004542 Thank you

LIsa, can you pass the FTDNA Y-DNA kit(s) number(s) of your cousins Y results? For surname comparisons, Y-DNA is a good place to start when using DNA results.

Hi everyone, I received my DNA results back today. I've a decent family tree on my maternal side but I've always hit a brick wall with my O'Sullivan lineage. A friend who is somewhat of an expert on Y-DNA suggested that I post here so that someone who is familiar with the O'Sullivan DNA groups may be able to look at my links and make a connection. If this doesn't work he is suggesting I upgrade to test a higher number of markers. What I'd like to understand is the origins of my O'Sullivan lineage if possible. I have imported my family tree from myheritage site so it should all be browse-able on my page. FTDNA kit is IN89739 Go raibh maith agaibh go léir

Looking at Y37 matches, I would say that you are not in the main O’Sullivan section of CTS4466, but in another branch which has very few O’Sullivan/Sullivan people. With Roy Walker being that close, more STRs testing could put you a little more to one side of the S1126 branch of CTS4466. When the tests go back on sale, you can test to a higher level and maybe show the right spot. Of course the Big Y700 test might be needed to get the discovery of new SNPs opening up the area of your results. The brick wall might be better served with a family finder test which shows the more recent tested relatives within the last few hundred years.

Liam, Ronald is spot on with his advice to you. I will add this. You should use as many sites as you can to upload your sample, then compare to other samples. Many people tend to stay on one site waiting for new samples to compare to. As a result they're not networking enough to find that one piece of information that launches their research. Also, use social media, look for Sullivan/O'Sullivan sites. Bottom line, you are in the correct study for this site. You'll end up either in the O'Sullivan Mor line (R-L270) or the O'Sullivan Bear line (believed by some prominent researchers to be BY149). Good luck with your research. Let us know if you need more help.

Hello, I've been doing family history at the amateur-level for about a decade but I'm new to the DNA side of things and hoping someone can tell me where to start down this journey. My 'white whale' as you could call it is my father's direct male-line ancestor Timothy O'Sullivan who was married to Ellen O'Neil. Their son Daniel Thomas Sullivan is the first record I can find of this couple, who appears in 1889 Graceville, Minnesota marrying Mary Agnes McLean, but he was born March of about 1853 in Canada, according to family lore and census records. We only know the name of his parents from Daniel's death record and that they were from County Cork—no information about any siblings or where he lived prior to 1889, although the early census records state he lived in Minnesota since about 1865 and moved to America as an infant. I've scoured pretty much every single Sullivan record in America and Canada at this point and can't find anything else that matches, mostly because I have so little information that I can't confirm or deny most records out there. I've collected every clue I can image and I've been recording them on the Geni world family tree ( So now I'm turning to DNA! The lucky thing is that he's the direct male-line ancestor to my father, who had his DNA tested at 23andme — his y-haplogroup is R-Z16521, which it would appear to link him with the Sullivan-Bere line. I'm not sure where to go next though - I looked at the Big Tree and it seems the clusters that Y-haplogroup forms includes Teagues, but I can confirm that there are none of those in my family tree (at least, they would have to be from a branch of Timothy like a brother in Ireland I don't know). Basically, where should I go next? Any advice would be heavily appreciated. Thank you! (my personal kit is B546570, haven't uploaded my father's yet)

Hello, my father's Gedmatch ID is KJ1789847. Mine is M100523 but i doubt that will be any more illuminating than my Sullivan father's. Thanks, Ronan, for sharing your family trees (I couldn't see yours on this website since we don't match); I don't see any obvious overlap but maybe it's much further back...

Ronan, I tested my cousin Darrell's brothers against your dad's Gedmatch kit and 1 brother matched on CH 7 at 8.7cm... 6.7 gens! This is the FIRST O'Sullivan match of any kind I have found! of course it could mean a lot of but exciting to me none the less

Hi All, I manage my cousin Darrell O'Sullivans DNA.. I have done Y testing but ALL matches seem to be Agee. Can someone please take a good look at his info and see if I am missing something. Kit B221252 Earliest known is John O'Sullivan who married Mary O'Connor. They are reported to be from Ireland and born between 1860-1870. My great grandfather Thomas Patrick O'Sullivan is their only know child and he was born Feb 1886 in Louisville KY. The little family settled by 1889 in San Francisco, CA. DO ANY ON YOU MATCH HIM?? Thank you for any help! I also have DNA for ALL living males from this line on Ancestry...

Kit 283806. Most of my father's family history is centered around the area where Ohio, Pennsylvania, and West Virginia connect. I did have communication from a lady living in Florida whose mother's DNA connected to mine but she has no more info other than that Sullivan branch was mostly located in the Bergen, New Jersey, and some in the New York area. She has since cancelled her membership in Ancestry so I am at a dead end. There was a John in her line that might have been my great grandfather, but no verification

I manage my brother's kit number 931297. We are hoping to solve our brick wall. Jesse Sullivan, born 1780 Baltimore, Md, died 1842 in Reading, Hamilton County, Ohio. Family story is that his family were Scotts-Irish. The one match with him is with a John Thornton Sullivan, born 1820 in Virginia. We cannot figure out the connection. Would appreciate any help and suggestion including any further testing we may need to do. Thank you in advance.

His closest match is DF19 which is an area that I know nothing about it. I moved his Y-DNA Results to the DF19 section. Contacting his DF19 match might be helpful. Also adding the family finder test to his and or your own DNA could maybe come up with some other folks who might match. The family finder test is most helpful for the last few hundred years or so. Getting both of you tested could identify some folks who might match only one of you. I have noticed that happening among the test results of my relatives. Joining the R1b-P312 group or the R1b and Subclades group could get the aid of somebody like Mike Walsh who knows more that I do about the DF19 section. The family finder test might be going on sale again for father's day and on the next holiday.

Thank you so much for your input. We have both been tested on other sites, but my atDNA is also on FtDNA. I will definitely check into the R1b-P-312 group. This is all new to me!

Anyone here know if they are a relation to this baseball player, Big Mike Sullivan? The article indicates that he is a cousin to my Great Grandfather, John W. Sullivan of Portland, Maine. If so, perhaps you could check to see for any matches to me or to my brother who Ydna tested, Rick Sullivan. Thanks! This is a little more information: Below is a sketch of Michael Joseph "Big Mike" Sullivan (1870-1906), a Major League baseball pitcher who played at least one season for the semi-pro or New England League Portland team. This is from the Daily Eastern Argus (Portland) 29 June 1895. Mike was a pitcher for the Washington Nationals (1889), Chicago Colts (1890), Philadelphia Athletics (1891), New York Giants (1891, 1896-97), Cleveland Spiders (1894-95), and Boston Beaneaters (1899). He led the National League in win-loss percentage (.750) in 1892. Mike was a cousin to John W. Sullivan, a prominent grocer and city councilor in Portland and great-grandfather of our member Deb Sullivan Gellerson. Mike was born in Boston, son of Galway immigrants Patrick Sullivan (1839-1916) and Winnifred Joyce Sullivan, and the grandson of Lawrence J. Sullivan (1799-1904) and Barbara O'Malley (1820-1892) who died in Boston. Played for the Nationals! He later became a Boston attorney. Lawrence Sullivan died in 1904 in Boston, aged 104 years, 4 months, 9 days! His parents were Michael Sullivan and Anastasia O'Malia, according to his death record. The Portland Sullivans were said to have been from the Parish of Ross, County Galway...

He is my first cousin three times removed. Lawrence Sullivan was my Greatgreat Grandfather and was from Derryrush, County Galway in Ireland. Barbara (O'Melia) O'Malley was from Rosmuc, County Galway which was 9 miles south of the Derryrush farmland.

Question, who was John W. Sullivan's father? John W. is not coming up on my records. If you have info (Birth death etc) please send along. My Great Grandfather was Michael Sullivan (Uncle to Big Mike).

Hello Beara Sullivans, I am an A6508 proven member of West Beara, per Big Y and the CTS4466 project. I won't show as such on FTDNA since I tested with YSeq, and don't like paying for loads of STR tests. I am a 1952 NPE in America due to donation, and can trace back to emigrants from Ireland during the potato famine via Autosomal results. I will visit Cork and Beara for the first time ever on April 25 -29, so hoping to meet up with a few cousins there. Checing Facebook now. RSVP

My Sullivan brother's Y 67 dna test shows 3 matches at the 67 level. One genetic distance 2, one 5, one 6. I don't know how to go any further with the research, but if there is a genetic distance of 2 and the charts say this is tightly related.. then to the chart that says distance of 2 is probably around the 1700 time frame. So, if this person that tested says they have a relative Patrick O'Sullivan b.1794 d.1849, then (assuming this is a researched line), this Patrick Sullivan or his father, should conceivably be my connection? I can only prove back to 1823 with my line. So, what's the next step here?!

Hi Ronald Howie... did you get a chance to look at the Y results on my brother, Richard Sullivan? Thanks!!

Looking at his STRs, I would guess that he will be in the S5488 section of DF21.

Dear Admins, I see my Kit B441279 is the very first one listed on the DNA results chart. Guess I can brag about being first at something :-) Actually my question is that the category is listed in the "Greg Hocking Ancestral Project" What does this mean? Is there anything additional that I can do to support the project? I know that I share a lot of Autosomal DNA with folks from the Sheepshead Peninsula, I'm working on understanding my Beara roots and know that I have connections on my paternal grandmothers side to Dublin and environs. I have 17 Big Y matches. Thanks for listening

Russel, No I have not signed up for that group. My BigY700 matches for R-S15280 has grown from 17 to 18 recently. Most are Ireland, a couple England and 1 Scotland, which is not a surprise. What is a bit of a surprise is that none of them share a surname with me, nor any surname from my direct tree. I would like to gain a better understanding of my DNA cousins. I will be going to the Sheepshead peninsula in my for a Sheepshead cousins DNA reunion with a Sullivan focus. It would be nice to have a better understanding of my Y DNA before showing up. Thank you.

Have you clicked on the "Block Tree" button on your home page? - That will create a tree for you (that will include R-S15280) - you may find that useful.
