The Liber Flavus Fergusiorum ("Yellow Book of the Ó Fearghuis"; RIA MS 23 O 48 a-b) is a medieval Irish text (dated to c. 1437-40) authored by the Ó Fearghuis, an Irish medical family of Connacht who were hereditary physicians to the Irish nobility.
The Ó Fearghuis name was conceived in the 7th century when Saint Máedóc of Ferns baptised and renamed the sons of Ailill, who was a 7th-great-grandson of Niall, High King of Ireland, as per his pedigree recorded in the Lives of Irish Saints, which reads: "Ailill, son of Rechtaide, son of Eitin, son of Felim, son of Caol, son of Áed, son of Ailill, son of Erc, son of Eógan, son of Niall of the Nine Hostages."The brothers mac Ailill thus became Fearghus and Faircheallaigh and were made Saint Máedóc's heirs to Rosinver Abbey and Drumlane Abbey. The Ó Fearghuis were themselves Irish nobility for descent from King Niall, originally based at Roscam, in Clann Fhergail. In the 13th century, they moved to what became County Mayo. In the 14th century, members of the family created the manuscript which came to be known as the Liber Flavus Fergusiorum.
The Liber Flavus Fergusiorum was composed at various times by several different scribes of the Ó Fearghuis, the principal one identifying himself as Aedh. Two translators, Seaán Ó Conchubair and Uidhisdín Mag Raighin, are named in colophons. Ó Conchubair translated a work on the Office of the Dead into Irish, while Mag Raighin translated the Life of John the Evangelist. The book derives its name from the Ó Fearghuis family, whose descendant Dr. John Fergus brought the manuscript from County Mayo to Dublin in the 18th century. Upon his death in 1761, it was held by his daughter, Frances Arabella Kennedy, whose grandson deposited it in the Royal Irish Academy in 1875.
Dubhaltach Mac Fhirbhisigh, also known as Dubhaltach Óg mac Giolla Íosa Mór mac Dubhaltach Mór Mac Fhirbhisigh, Duald Mac Firbis, Dudly Ferbisie, and Dualdus Firbissius was an Irish scribe, translator, historian and genealogist. He was one of the last traditionally trained Irish Gaelic scholars, and was a member of the Clan MacFhirbhisigh, a leading family of northern Connacht. His best-known work is the Leabhar na nGenealach, which was published in 2004 as The Great Book of Irish Genealogies, by Éamonn de Búrca, more than 300 years after it had been written.
Saint Máedóc of Ferns, also known as Saint Aidan, or Saint Mogue, was an Irish saint who was the first Bishop of Ferns in County Wexford and the founder of thirty churches.
Niall "Noígíallach", or in English, Niall of the Nine Hostages, was a semi-mythical Irish king who was the ancestor of the Uí Néill dynasties that dominated the northern half of Ireland, reigning from the 6th to the 10th centuries. Irish annalistic and chronicle sources place his reign in the late 4th and early 5th centuries, although modern scholars, through critical study of the annals, date him about half a century later. He is presumed by some to have been a real person, or at the very least semi-historical but most of the information about him that has come down to us is regarded as legendary.
The Connachta are a group of medieval Irish dynasties who claimed descent from the legendary High King Conn Cétchathach. The modern western province of Connacht takes its name from them, although the territories of the Connachta also included at various times parts of southern and western Ulster and northern Leinster. Their traditional capital was Cruachan.
Mongfind —meaning "fair hair" or "white hair"—is a figure from Irish legend. She is said to have been the wife, of apparent Munster origins, of the legendary High King Eochaid Mugmedón and mother of his eldest three sons, Brión, Ailill and Fiachrae, ancestors of the historical Connachta. She was Eochaid's first wife; his second wife, Cairenn, gave birth to Niall of the Nine Hostages. Several tales depict Mongfind as an adversary of Niall. Mongfind is also said to have been the sister of Crimthann mac Fidaig, King of Munster and the next High King of Ireland, whom she is said to have killed with poison in a bid to make her son king. She drank the poisoned drink to convince Crimthann, and died soon after at Samhain.
Diarmait mac Cerbaill was King of Tara or High King of Ireland. According to traditions, he was the last High King to follow the pagan rituals of inauguration, the ban-feis or marriage to goddess of the land.
The O'Donnell dynasty were the dominant Irish clan of the kingdom of Tyrconnell, Ulster, in medieval and early-modern Ireland.
Rossinver or Rosinver is a small village in north County Leitrim, Ireland. The village is home to a retired monastery of the same name and is at the southern shore of Lough Melvin, home to two rare species of trout – the Gillaroo and the Sonaghan – as well as the common brown trout. There is a fishery at Eden Quay and boats and gillies are available locally. There is a mile-long river walk to Fowley's Falls on the Glenaniff River which follows a series of waterfalls.
Leabhar Chlainne Suibhne is a 16th-century Donegal manuscript written in Irish. While there is a substantial amount of religious material, it is principally interesting for containing a historical tract concerning the Clan Suibhne. It is now held in the library of the Royal Irish Academy as MS No. 475.
The Uí Ceinnselaig, from the Old Irish "grandsons of Cennsalach", are an Irish dynasty of Leinster who trace their descent from Énnae Cennsalach, a supposed contemporary of Niall of the Nine Hostages. Énda was said to be a grandson of Bressal Bélach and a first cousin of Dúnlaing mac Énda Niada, eponymous ancestor of the rival Uí Dúnlainge.
The Battle of Confey or Cenn Fuait was a battle fought in Ireland in 917 between the Vikings of Dublin and the Irish King of Leinster, Augaire mac Ailella. It led to the recapture of Dublin by the Norse dynasty that had been expelled from the city fifteen years earlier by Augaire's predecessor, Cerball mac Muirecáin of Uí Fáeláin, and his ally Máel Finnia mac Flannacáin, the King of Brega.
The Uí Briúin were a royal dynasty of Connacht. Their eponymous apical ancestor was Brión, son of Eochaid Mugmedon and Mongfind, and an elder half brother of Niall of the Nine Hostages. They formed part of the Connachta, along with the Uí Fiachrach and Uí Ailello, putative descendants of Eochaid Mugmedon's sons Fiachra and Ailill. The Uí Ailello were later replaced as the third of the Three Connachta, through genealogical sleight of hand, by the Uí Maine.

Abbán moccu Corbmaic, also Eibbán or Moabba, is a saint in Irish tradition. He was associated, first and foremost, with Mag Arnaide and with Cell Abbáin. His order was, however, also connected to other churches elsewhere in Ireland, notably that of his alleged sister Gobnait.
Tuileagna Ó Maoil Chonaire was an Irish poet.
The Uí Fiachrach were a royal dynasty who originated in, and whose descendants later ruled, the coicead or fifth of Connacht at different times from the mid-first millennium onwards. They claimed descent from Fiachrae, an older half-brother of Niall Noigiallach or Niall of the Nine Hostages. Fiachrae and his two full brothers, Brion and Ailill, were the collective ancestors of the Connachta dynasty that eventually became the new name of the province. Their mother was Mongfind.
O'Farrelly is the first anglicised form of Ó Faircheallaigh, an Irish noble family of County Cavan who were historically the Abbots of Drumlane. The patronym means "descendant of Faircheallaigh", whose name means "super war". Faircheallaigh was made the heir of Saint Máedóc of Ferns in the 7th century and his descendants were the hereditary Abbots of Drumlane for 7 centuries until David Ó Faircheallaigh was elevated as Bishop of Kilmore. The surname became Farrelly and Farley.
The Northern Uí Néill is the name given to several dynasties in north-western medieval Ireland that claimed descent from a common ancestor, Niall of the Nine Hostages. Other dynasties in central and eastern Ireland who also claimed descent from Niall were termed the Southern Uí Néill. The dynasties of the Northern Uí Néill were the Cenél Conaill and Cenél nEógain, named after supposed sons of Niall: Conall and Eógain.
The Breac Maodhóg is a relatively large Irish house-shaped reliquary, today in the National Museum of Ireland. It is thought to date from the second half of the 11th century, and while periods as early as the 9th century have been proposed, the later dating is believed more likely based on the style of its decoration.
