The O'Neill's of the Fews and the O'Neill's of Puerto Rico

The O'Neill's of the Fews and the O'Neill's of Puerto Rico , share many things in common, one of them being the island of Puerto Rico, were many of the O'Neill's of the Fews were born in the 1800's ,and served in the military of Puerto Rico. On the island ,there must be a few descendants of the O'Neill's of the Fews, yet to be found in various areas of Puerto Rico, due to the son's of Don Arturo O'Neill O'Keffe, 2nd Marquez del Norte, who remained on the island and few records have been found, due to the lack of interest, by many of the current O'Neill's in Puerto Rico. One line is established to have a different origin than those of the Fews. These O'Neill's are the descendants of Don Juan O'Neill , whose oral history is totaly different of that of the O'Neill's of the Fews, but more in line with the O'Neill's of Tyrone.

Based on the marriage record of Don Patricio O'Neill Garcia, dated 1778, we do know that these O'Neill's were in Puerto Rico , long before any of the O'Neill's of the Fews, also Don Arturo O'Neill O'Keffe, 2nd Marquez del Norte , was born on St.Croix in 1783, and Don Juan's grandson , Don Jose O'Neill was married the same year that Don Arturo, was married in the year 1802. I researched into Lt.General Felix O'Neill of Creegan , who was born circa 1720's, as the possible father of Don Juan O'Neill, but dates and oral history do not match, Don Felix O'Neill of Creegan , did have a son named Juan O'Neill Valera, who later became a Captain General, but he was born in 1765,and matched to the marriage date of Don Patricio O'Neill Garcia ,shows that Don Juan O'Neill Valera, could have been only 13 years old.

Another name I have looked into is Captain General Felix O'Neill's of the Fews, who was married twice, and did have two sons named Juan and Jose O'Neill Ranisol. But there is no mention of Don Felix O'Neill of the Fews in the Caribbean, although it's very likely he was, but no records of him in military service in the Spanish Netherlands, to my knowledge.

Oral history states that the progenitor of our line was a tall man of blue eyes and dark hair. He arrived in Puerto Rico with his brother both military men from Ireland of Irish ancestry . There are said to have fought in the land were people wore Wooden Shoes and there were windmills ( The Spanish Netherlands, modern day Belgium ) . He was said to have been involved in Piracy and had a violent temper . In our family most males are between the height of 6 ft 4 inches and 5 feet 11 inches ( 193.04 centimeters to 180.34 centimeters )and weight around 230 lbs to 260 lbs. (average of 113 kilograms) . Often of a muscular built with broad shoulders and strong arms. Usually hair turn completely white around the ages of 30 and 40 years. Most males are of dark hair but a few have been nicknamed "Cano" a word to describe some of blond hair. This O'Neill's true oral history show they lived in Spain before migrating to the Spanish Netherlands around the 1600's.
Family oral history states that our origins are from a man named Edmundo , Eamon or a Enrique Rua O'Neill who fought in the Spanish Netherlands . Also men involved in piracy with men named Rocco ( Richard or Ricard) , Gill ( Guillermo) , Juan ( Sean, John) and the head of the clan was a man named Conn or Constantino. This family was ruled by eight heads and all lived in one area were they would all meet after long campaigns or raiding. There are also accounts of a woman named Rose involved in the family or mother of my ancestor.

These men had great knowledge of the sea and the Caribbean. It's believed Patricio O'Neill Garcia had a brother possibly named Jose O'Neill Garcia who left Puerto Rico never to return possibly migrated to one of the neighboring islands or back to Spain or Spanish Netherlands.There is second story that is found among other O’Neill’s of Puerto Rico, is that of the daughter of a O’Neill, had two or three male children with a Indian or African salve and when the father found out he took back his daughter to Ireland or Spain. The two children took their mother’s surname and so did their descendants.

I have researched for the name Edmond O'Neill , but found only records of a Edmond, who died fighting against his cousin Hugh O'Neill, Earl of Tyrone. This Edmond was the son of Shane 'Diomas' O'Neill, son of The First Earl , Con Bacagh (The Lame) O'Neill, who died in 1588. Some accounts have Edmund O'Neill (McShane) being hung by his cousin Earl Hugh O'Neill in 1602. Family oral history states that he died in a battle. In search of the name Rose or Rosa I found.


Rose the name of the sister of Edmond who married into the McDonnell clan.

There are various Rose or Rosa O'Neill's and countless Henry's and Conn's among all the clans that could have .

Rose O'Neill of the Fews married a man named Phillip O'Reilly of Co. Cavan.

Rose O'Neill of the Fews 1672-1757 married a Maurice O'More of Co. Mayo.
Rose O'Neill daughter of Sir Henry O'Neill of Shane's Castle of the Clanaboy. She married The Earl of Antrim Randall McDonnell circa the 1600's.
Rose O'Donnell who married Art Oge O'Neill . She was the daughter of Don Manus O'Donnell , Lord of Tyrconnell.
Rose O'Neill , daughter of Teige O'Neill and Mary O'Donnell. She married a MacCallum of Scotland.
Rose McGuiness who married Shane O'Neill , last of the lord of the Clanaboy of Shane's Castle.
Rosa O'Neill 1582- d. Nov 1st 1660 married Owen (Eugenio) Roe O'Neill parents of Henry (Enrique ) Roe O'Neill. She was the sister of Cahir O'Doherty was once married to Cathbar O'Donnell brother of the Earl of Tyrconnell. She lived in Louvain and in 1651 settled in Flanders and lived in Brussels. Currently buried in the Franciscan College of St. Anthony of Padua in Lovain.

There is a distant Rose associated with Henrietta O'Neill daughter of Sarah O'Neill and Henry O'Neill. Henrietta O'Neill married Colonel John Comerford and were parents of a Jose Comerford y O'Neill. But time line of birth dates does not match nor the Y-DNA of the Comerfords.

The Aodh Athlaman and the O'Neill Core Theory.

Why was Aodh Athlaman d. 1033 stated to be the last of his race? this leads to a theory of a " O'Neill core group" of a selected male lineage of the Royal O'Neill's and the House of Tyrone. If Aodh was the the last of his race? Was he not of the Ui Neill, or not of the native Ulster population? Let's say Aodh was the last of his race this would mean that his bloodline was reduced to a selected gene pool, where generations later the descendants of Aodh Athlaman, would have a Hapotype, unique only among a few selected O'Neill's males. Then the only way for the O'Neill Royal clan to survived was to absorb others into the clan to remain in power. Only way the "O'Neill Core Theory" can be proven is by finding a unique Haplotype shared by the O'Neill's and MacLaughlin's their closest kindred.

From the Gleanings of Ulster History , Seamus O Ceallaigh 1952

" For six generations in sequence the family depends upon a single individual to maintain the succession; no brothers or uncles are mentioned ,and the L.E. expressly states that Aodh was the last of his race. Now it was altogether exceptional for these ruling families to be reduced in the reginal succession of single heirs. "

" Following the ordinary law in the community, there must have been as many daughters as sons. If this achievement provokes any sense of mystery, I leave the probing of it to the student of genetics or those curious about the trend of social proprieties , but obviously this factor was turned into a source of strength in war and administration."

"It's is conceivable that O'Neill lineage may have been spun out to a single filament in 1160, but the matter in which the facts are represented to us is not convincing."



L.E. (Lebor Eoganach)

There are various SNP's that define the O'Neill's currently tested R1b1b2a1b5, the majority of the O'Neill's tested are R1b1b2a1b, R1b1b2a1b5b, I2b1a ,and the O'Neill's of Puerto Rico R1b1b2a1a4. It's not known to what extent the Danes, Norse, and Normans influnced the O'Neill's of Tyrone, and this could be the reason why we have various SNP's among the O'Neill's tested. There could be also been MacNeill's and McEvies who were gallowglass who adopted the surname O'Neill in Ulster , yet there is the adoption of John Geoghegan of Castle Bunowen in Co. Galway , that in 1807 adopted the surname O'Neill and his descendants from then on are known as O'Neill's . There are plenty of O'Neill's who are Geoghegan's at the moment ,and do not realize this fact. Again, Let's look at various clans who are not of the house of Tyrone , but do have the O'Neill surname in current modern times due to various reasons.

The Neylon's of Co. Clare of the Niallain sept, the Neilan surname can easily be changed to O'Neill or O'Neil with the droping of the ' an' suffix at the end of the surname. Then we have the Nihill's of Co.Clare origins of the O'Neighill sept located in the Barony of Bunratty of Thomond. These clans or septs are not of the O'Neill's of Ulster , or of the O'Neill Royal House of Tyrone.



If we eliminated and totaly ignore that Niall Glundubh was born in Norway circa 850 a.d., and the Anglo-Saxon Chronicle that describe Niall, as the brother of Sigtrygg Caech of the Ui Imar. Then it's very likely that Niall Glundubh MacAedo was of the SNP R1b1b2a1b5b and of the Ui Neill clan. This would explain the small amount of currently tested O'Neill's who are R1b1b2a1b5b, since Aodh Athlaman was stated to be the "last of his race" in the Lebor Eoganach. The question is about the R1b1b2a1b2 O'Neill's! Who are these men? my theory is that they are originally men of the Airghialla and Oriel kingdoms , that were reducec to subkingdoms under the Cenel Eoghain during the 7th and 8th centuries.

The O'Neill's Y-DNA

The O'Neill's Y-DNA




Only over 200 , or so O'Neill's have currently been tested their y-dna, and this is only a small amount compared to the vast O'Neill's through the world. Perfect example are the O'Neill's in the Caribbean, France, Portugal, Spain ,and South America. What we do know is that from the current O'Neill's tested (200 O'Neill's ) the majority belong to the SNP R1b1b2a1b , and the ones who have not tested for their SNP are R1b1b2 , and very likely they will be R1b12a1b once tested. It's speculated that they all seem to share a common ancestor possibly around 950 a.d. , who was this common ancestor? It's not known , but what is interesting is that they do match the surname Sterling and Williams, very well. A theory is that this group of O'Neill's were part of a tribe absorbed into the Cenel Eoghain, during the reign of the Domnhall of Armagh or better known as Domnhall Ard Macha Ua Neill ,or they were absorbed into the Cenel Eoghain in earlier times.

The O'Neill's y-DNA brake down to several different Haplogroups.

1. R1b1b2a1b5b O'Neill's the MRCA Niall of the Nine Hostages ,and founder of the Ui Neill dynasty, not of the O'Neill's surname.

2. I1b1a O'Neill's the MRCA is unknown , but this SNP is found in Spain and Sardinia.

3. R1b1b2a1b5 O'Neill's the MRCA is unknown. What is known is that this SNP is found in Finland, Norway ,and Sweden.

4. R1b1b2a1b O'Neill's the MRCA is unknown, yet this is the SNP found in the majority of O'Neill's currently tested out of 200 +.

5. R1b1b2a1a4 O'Neill's of Puerto Rico, the MRCA is Don Constantino O'Neill of Spain of the late 1600's . These O'Neill's haplotype is unique ,and has a strong connection to a group of similar haplotypes in Yorkshire, England, the Shetland islands , and Sweden, but no matches in any database the closest matches is estimated around 800 to 900 a.d.

There are 5 distinct SNP's and various septs, but only two of the SNP's , the progenitor or MRCA is known, and many of these O'Neill septs do not have a modal y-dna haplotype or a SNP. These various O'Neill's to my knowledge do not have a modal Haplotype,or have anyone that as aquired a y-dna tested. The O'Neill's of the Magh da Chonn, The O'Neill's of Thomond, The Clannabuidhe O'Neill's, The O'Neill's of Cor, The O'Neill's of Feevag, The O'Neill's of Ivowen, The Johnston Baronets of New York, and the O'Neill's of Fews (Spain). Of these septs none of their MRCA's y-dna is known.

The O'Neill's of the Fews MRCA or progenitor is Aodh of the Fews d.1475 , one of his descendants Sir Henry O'Neill of the Fews (Don Enrique O'Neill of the Fews) is the progenitor of the O'Neill's of the Fews in Asturias and Sevilla , Spain. No one of their respected sept as come forward to acquire a y-dna test ,and we do not know their SNP or Haplotype.

The Clannabuidhe O'Neill's progenitor is Aodh Buidhe SNP unknown .

The O'Neill's of Tyrone progenitor Niall Glundubh MacAedo d. 919 SNP unknown .

The O'Neill's of the Fews and Clannabuidhe both are of the House of Tyrone ,and it is assumed that they both share a common ancestor in Aodh 'The lazy Youth' O'Neill 1176 -1177. Also, the Maclochlainn and O'Neill's is assumed to share a common ancestor in Domnhall Ard Macha Ua Neill 956 - 980 the grandson of Naill Glundubh MacAedo.
