Earl of Tyrone
The Earl of Tyrone is a title created three times in the Peerage of Ireland.
It was first created as part of the Tudor attempt to establish a uniform social structure in Ireland by converting the Gaelic kings and chiefs into hereditary nobles of the Kingdom of Ireland. Under brehon law, clans were effectively independent, and chose their chiefs from the members of a bloodline – normally, but not always, a close relative of the previous chief; the clan as a whole generally had a voice in the chief's decisions. Also, acknowledged sons of a clan member were members of the bloodline, even when not begotten in lawful marriage. The holder of a title, on the other hand, was subject to the Crown, but held his lands by hereditary right, which the Crown would help to enforce; the rest of the clan were usually now his tenants. Illegitimate sons had no right of succession under the new system unless expressly granted.
The title in the Peerage of Ireland was created again in 1673 for Richard Power, 6th Baron Power, the Anglo-Norman peer and Restoration politician, along with a large grant of land in County Waterford, at the other end of Ireland. He was also given the subordinate title of Viscount Decies; both titles became extinct upon the death of his younger son, the third earl, in 1704; he left an only daughter, Lady Katherine Power, but both titles descended by patent to male heirs only.
It was created a final time in 1746 for Marcus Beresford, 1st Viscount Tyrone, son-in-law of the last Power earl. His son was created Marquess of Waterford in 1789, and the title has since been a subsidiary title of the Waterford title.
Earls of Tyrone, first Creation (1542) 
The king or chief of the O'Neills of Tyrone, Conn Bacach O'Neill, went to Greenwich and submitted to Henry VIII of England and of Ireland in 1542; he renounced his chieftainship, the style of "The O'Neill" and his independence. In exchange, he was created Earl of Tyrone, which was by the charter to descend to his illegitimate son Matthew or Ferdoragh O'Neill, who was also created Baron of Dungannon, which was always to be held by the heir to the Earldom; this was a substantive title, which gave Ferdoragh a seat in the Irish House of Lords, not a courtesy title. This adaptive process, known as "surrender and regrant", was taken up by other Irish clan chiefs.
This passed over Conn's legitimate sons; the eldest, Shane O'Neill, was only about twelve at the time. When he grew up, Shane (who is remembered as an Diomais, "the Proud") claimed to be The O'Neill (in Irish: Uí Neíll), and there was civil strife among the Cenell Eoghain; Shane was victorious, Ferdoragh was killed, Conn was driven out of Tyrone, and died in the Irish Pale, the area of Ireland directly governed by the English.
In English law, Ferdoragh's eldest son, Brien O'Neill, then succeeded to the Earldom; in practice he continued to be called Lord Dungannon. Queen Elizabeth, newly come to the throne, proposed to recognize Shane as Earl, since he actually ruled Tyrone and was the eldest legitimate son; but the negotiations collapsed. Brien was killed in 1562, while still young and unmarried, by his cousin Turlough O'Neill, the tanist of his uncle Shane (and a grandson of the brother of Conn Bacagh, the first Earl). Shane died in 1568, whereupon the English generally supported Brien's younger brother Hugh O'Neill against Turlough, who, as effective leader of the clan, was perceived to be the greater threat to English control of Ireland. In 1585, Hugh was recognized as Earl of Tyrone; in 1593, Turlough surrendered to him the position of "The O'Neill".
Hugh O'Neill's career as unquestioned leader of the O'Neills became a series of quarrels with the English government: like many great feudal lords, he rebelled in the Nine Years' War, was proclaimed a traitor, and ultimately submitted to the Crown at the Treaty of Mellifont in 1603. Despite the Anglo-Spanish peace treaty of 1604, in 1607 O'Neill, his brother-in-law the Earl of Tyrconnell, and several of their followers fled to Europe, expecting the Spanish to invade Ireland with an army. He was attainted the year after this Flight of the Earls, and the attainder was confirmed by the Parliament of Ireland in 1614; at which point the Earldom became forfeit under the common law.
Notwithstanding this attaintment, Earl Hugh, followed by his sons, continued to claim to be Earl of Tyrone, until the last legitimate son died unmarried, some time between 1641 and 1660. (It is not entirely clear which of his sons were legitimate: he was married four times, not always legally divorced, and it is not clear who were the parents of Conn O'Neill, chief of the O'Neills around 1650.) At this point the Irish title became extinct, as well as forfeit, but the descendants of Earl Hugh's illegitimate brothers acted as The O'Neill, and called themselves Earl of Tyrone by Spanish grant, for the rest of the century.
- Heirs who did not live to succeed are indented.
- Conn O'Neill, 1st Earl of Tyrone(c. 1484–1559)
- Matthew O'Neill, 1st Baron Dungannon (c. 1520–1550)
- Brien O'Neill, 2nd Earl of Tyrone, 2nd Baron Dungannon (c. 1540–1562)
- Hugh O'Neill 3rd Baron Dungannon, 2nd or 3rd Earl of Tyrone. (c. 1550–1616) attainted 1608, attainder confirmed by Irish Parliament 1614.
- Hugh O'Neill, Baron Dungannon (c. 1586–1609) attainted 1608.
Baron Dungannon 
The Barony of Dungannon created for Matthew or Ferdoragh O'Neill was limited, by the terms of the patent, to his descendants who were heirs apparent to the Earldom of Tyrone. This provision would have meant that it acted like a courtesy title: when an Earl of Tyrone had an eldest son, or an eldest grandson by a deceased eldest son, that heir would be Baron Dungannon; when there was no heir apparent, the Barony of Dungannon lapsed until there was.
So when Matthew died, his son Brien became Baron Dungannon. However, when Conn Bacach died the next year, Brien was not recognized as Earl of Tyrone, but continued to be called Baron Dungannon until he was killed by Turlough Luineach O'Neill, Shane the Proud's tanist.
His younger brother Hugh O'Neill was called Baron of Dungannon until 1585, when he received a charter confirming him as Earl of Tyrone. The same charter confirmed his son Hugh, the eldest son of his second wife, as Baron Dungannon; Earl Hugh's first marriage was invalid, and his children by that marriage illegitimate.
The following men were known as Baron Dungannon:
- Matthew O'Neill, 1st Baron Dungannon, (bef. 1624 - 1558), cr. 1542.
- Brien O'Neill, Earl of Tyrone (- 1562), de jure Baron Dungannon 1558-9, styled Dungannon 1558-1562.
- Hugh O'Neill, Earl of Tyrone, (- 1616) styled Baron Dungannon 1562-1585, never de jure: before his brother's death, he was not heir apparent, for his brother could have married and had sons; after his brother's death, he was de jure Earl of Tyrone, but not Baron Dugannon by the limitation.
- Hugh O'Neill, Baron Dungannon, (c. 1575 - 1609), styled Baron Dungannon, 1587–1608, de jure from birth. Title forfeit 1608.
Since the younger Hugh O'Neill was attainted with father in 1608, the title is forfeit, and is now extinct. Young Hugh went to Rome with his father, and died there in the summer of 1609.
Earl Hugh and his family continued to lead the O'Neills of Tyrone from abroad; they also had the title of Earl of Tyrone recognized in Spain in the form of Conde de Tyrone. "Though no longer recognized in England, it was granted by Spanish kings to a line of O'Neills in rightful succession to the of the seventeenth century".
- Hugh O'Neill (c.1550–1616), the attainted Earl.
- Henry O'Neill (c.1586–1610) Earl Hugh's son by Joan O'Donnell, his second wife; Colonel of the Irish regiment in the Spanish service in Flanders; Knight of Santiago. Accompanied his father in his flight, and was attainted 1608, confirmed 1614. He is omitted from an account of his father's family in 1617; he is noted as dead in 1621
- Shane O'Neill (Juan, John, Sean: 18 October 1599-27 Jan 1641), Earl Hugh's son by Catherine Magenis, his fourth wife. Succeeded his father as Earl of Tyrone, his brother as Colonel; Knight of Calatrava; Major Domo at Madrid, 1638; died in the siege of Barcelona.
- His younger brothers died young: Conn (c.1601–1627) was left behind in the flight, went to Eton, and died in the Tower of London; Brian (1604–1617) went to school in Brussels and was killed there, being found hanged with his hands bound.
- Hugo Eugenio O'Neill, his son, was legitimated at Shane's death by Philip IV of Spain but died young. Shane's will provided that Hugo Eugenio be taught Irish, so he could be an effective leader of the O'Neills; it also provided an elaborate system of succession if Hugo Eugenio died childless, as did happen.
- Conn O'Neill (Con, Constantino, died before 1660), son of Cormac O'Neill, the younger brother of Earl Hugh who died in the Tower of London, was named as second heir in Shane O'Neill's will, if Hugo Eugenio died childless; by the law of the Kingdom of Ireland, he would be the last heir to the Earldom, if restored. Since he died before Hugo Eugenio, he does not appear to have called himself Earl, but Owen Roe O'Neill, Earl Hugh's half-nephew and a general in the War of the Three Kingdoms, acknowledged "that all the immediate right to the earldom of Tyrone belongs to Don Constantino, who is in Spain" and that while he lived, Owen Roe himself "could claim nothing".
By 1660, therefore, the Earldom of Tyrone was extinct as well as forfeit. Nonetheless, the last collateral O'Neill descendants of Mathew "Ferdocha" O'Neill, continued to use the title in Spain until 1692.
- Hugh Dubh O'Neill, (c. 1610-c.1666), nephew of Owen Roe O'Neill (by his brother Art Oge) and so grandnephew of Earl Hugh, and commander under his uncle in Ireland, where he held Limerick against Henry Ireton during a long siege. Petitioned Charles II in October 1660, after the English Restoration, to be restored to the Earldom of Tyrone.
- Hugh O'Neill (after 1644-c. 1670), grandson of Owen Roe O'Neill by his son Henry Roe O'Neill. Knight of Calatrava 1667.
- Owen O'Neill, grandnephew of Owen Roe O'Neill, whose younger brother Con had a son Brian, father of this Owen. Educated at Rome; executor of a will 1679, died after 1689. After Owen, no-one claimed the Earldom of Tyrone until the 19th century.
- Don Bernardo O'Neill, (circa 1619-1681) Colonel of the Irish regiment of Tyrone, nephew of General Eoghan Roe. Born in Armagh, served as a Captain in Flanders starting in 1636. Fought in the War of the Confederacy, returned to Flanders and was given permission to raise and Irish regiment in 1663. In 1673, "became Earl of Tyrone after the death of Hugo, son of Henry mac Eoghain Rua". Died 1681 in Barcelona.
- Eugenio O'Neill, after the death of Don Bernardo in 1681, "the titular colonel was the eighth Earl, a young boy also called Eugenio O'Neill", he was claimed as a grandson of General Eoghan Rua through a son named Brian. He was still a minor and titulary colonel of the Regiment of Tyrone on 18 April 1689.
Later claimants 
By this point, the claim to the Earldom of Tyrone became intertwined both with the position of the O'Neill of Tyrone and the wider position of chief of all the O'Neills of Ulster. Not all the claimants to the Gaelic offices claimed the Earldom: the descendants of Shane the Proud were inaugurated as the O'Neill by the ancient ritual, by which the O'Hagan put golden shoes on their feet on May Eve, without calling themselves Earls.
The leadership of the O'Neills as a whole had usually been held by the O'Neills of Tyrone; but their distant cousins the O'Neills of Clanaboy or Clandeboye in Antrim had also sometimes held it, most recently Art mac Aodha O'Neill, from 1509 to 1514, when the first Earl was young. They, like the O'Neills of Tyrone, spent much of the seventeenth century fighting for the Catholic powers; in 1740 they relocated permanently to Portugal.
Don Jorge O'Neill of Clanaboy and Lisbon submitted his pedigree to the Ulster office of Heralds; in 1896, he received a letter from Sir Henry Farnham Burke, Somerset Herald, acknowledging that he had proved his descent from the royal descent from the Kings of Ireland, and his collateral descent from Hugh O'Neill. Although collateral descent from the grantee does not confer a peerage, he assumed the style of Conde de Tyrone, but his descendants use the title Prince of Clandeboye.

- Micheline Kearney Walsh: "The Will of John O'Neill" (1976); before the will was published, there were theories than this Conn was an elder brother of Owen Roe O'Neill; or a son of one of Owen Roe's elder brothers; and so descended from Owen Roe's father, Art McBaron O'Neill, an illegitimate half-brother of Earl Hugh (Art's epithet arises from his being the son of Ferdoragh (Matthew), Baron Dungannon). This would not bar him or Owen from being leader of the O'Neills; but it would mean they were not heirs to the Earldom.
