Fragmentary Annals of Ireland
The Fragmentary Annals of Ireland are a Middle Irish combination of chronicle from various Irish annals and narrative history.

, so called because only fragments remain of a seemingly longer work, these again copied by Mac Fhirbhisigh in the 17th century from a 15th century manuscript. The fragment which deals with Cerball's lifetime ends in the early 870s, so that the last fifteen years of his life are missing. Joan Radner, editor and translator of the modern edition of the Fragmentary Annals, argues that these were compiled at the court of Cerball's great-great-grandson Donnchad mac Gilla Pátraic. Although called annals, these are closer to narrative history and are derived from a number of sources. The basic framework is from the Chronicle of Ireland, but to this has been added a variety of material whose source is unknown, perhaps including early saga

s, which concerns Cerball. The Fragmentary Annals were intended to magnify Cerball's achievements, and to present his dealings with Vikings and Norse Gaels in a favourable light.

If the various annals are partisan, the remaining sources which concern Cerball are notably unreliable. Perhaps inspired by the Fragmentary Annals, which offer some positive views of Vikings and may have been popular in the Norse Gael Dublin of the 11th century, many Icelandic genealogies include Cerball—Kjarvalr Írakonungr—as an ancestor.

 was Máel Sechnaill mac Máele Ruanaid who was married to Cerball's sister Land. Cerball in turn was said to be married to a daughter of Máel Sechnaill.

The first report of Cerball is in 846, when Vikings attacked into northern Osraige, destroying a church at Coolcashin (near Galmoy
Galmoy
Galmoy is a village in the barony of Galmoy, County Kilkenny in the southeastern part of the midlands of Ireland.-See also:*List of towns and villages in Ireland*Galmoy Mine...

), and plundering an unidentified settlement at Cúl Maine. Here the raiders were besieged for a fortnight by Cerball's army and lost heavily. The following year Cerball defeated an attack by Vikings from the Irish midlands, perhaps from Dublin, led by one Hákon. This battle is said by some sources to have taken place at Carn Brammit, a site which can no longer be identified.

The late Annals of the Four Masters record an invasion of Osraige in 848 by the Uí Cheinnselaig

 of southern Leinster, led by their king Echtigern mac Guaire. Cerball played a part in Echtgern's removal in 853. The Annals of Ulster report that Echtigern was killed "deceitfully" by Cerball and one Bruatur of Áed, and that Bruatur was killed by his own household a week later.

In 854 the Fragmentary Annals say that Cerball was sent into Munster by his brother-in-law to collect tribute and hostages.

In 855 he is said to have slaughtered a Viking force under a certain Rodolb. In the aftermath of the battle Cerball was captured by other Vikings, but succeeded in escaping. Shortly afterwards Cerball aided a force of Danes led by a chief named Horm in their war with the Norwegians. The Danes may well have settled at what is now Waterford

, although this is far from certain. These allies were not sufficiently strong to prevent Máel Sechnaill from taking hostages and tribute from Cerball in 858, but Cerball and Ímar campaigned in Leinster that year, and also against the Norse-Gaels in Munster. The following year, together with Amlaíb Conung, they raided Máel Sechnaill's lands in Mide

In 860 Cerball defeated a force of Norse who were raiding in Osraige, and later in the year he joined Máel Sechnaill on campaign against Áed Finnliath

Áed and Flann

Máel Sechnaill died in 862 to be succeeded by Áed Finnliath, who married his widow, Cerball's sister. Also in 862, Cerball is reported to have defeated a Norwegian fleet under one Rodolb, although it is not clear that this is the same Rodolb who was defeated in 855. In 864 the Fragmentary Annals of Ireland report that the men of Leinster and their Norse allies raided Osraige in revenge for Cerball's raid, and that Eóganachta of Munster took advantage of this to attack him, so that Cerball raided both his neighbours and caused much destruction. The same year he is said to have attacked the neighbouring Déisi

In 870 Áed Finnliath brought a large army to Leinster and Cerball accompanied him. The army of the Osraige was camped apart from Áed's main force, and was attacked by the Leinstermen. Although Cerball drove them off with heavy loss, Cennétig son of Gáethíne, a kinsman of Cerball, was killed in the battle. With a final notice of an expedition to Connacht

 and Munster in 871, the Fragmentary Annals are interrupted. In the Annals of Ulster, nothing more is said of Cerball until his death in 888. The next king of Osraige was his brother Riacán, but the kingdom lapsed into relative obscurity for many years afterwards, until Cerball's great-great-grandson Donnchad mac Gilla Patráic became king in 1003.

Kjarvalr Írakonungr

While it is unsurprising that Cerball's great-great-grandson should have commissioned a work in which his most illustrious ancestor was portrayed in a heroic light, it is less obvious why Cerball in particular should have such a prominent place in the Icelandic sagas and in the genealogies of the founding families of Iceland

Some of these names are Irish: Kormlöð is the common name Gormflaith, Eithne too is clearly Irish as is Dufnial. It is doubtful whether Rafarta or Fridgerd are Irish, and there are clearly difficulties with the supposed number of generations. Insofar as any conclusions have been reached by historians of Ireland, it appears that the supposed descendants of Cerball left for Iceland in the generation before Donnchad mac Gilla Patraic, towards the end of the tenth century. Given the likely date at which the Landnámabók was compiled, this is rather too far in the past for the genealogies to be considered very reliable. Adding to the uncertainty, the genealogies of the Osraige themselves were subject to comprehensive rewriting in Cerball's time and immediately afterwards, attaching them to the Laigin of Leinster.

It has been suggested that the importance of Cerball in Icelandic writings stems from the popularity of the Fragmentary Annals of Ireland among the Norse-Gaels of eleventh century Ireland, who passed these accounts on to the Icelanders, who then attached this famous and warlike king to their ancestry. Whether Cerball was in fact an ancestor of many prominent settler families is, however, of rather less importance than the fact that the Icelanders considered it worth reporting their descent from Cerball mac Dúnlainge, whether real or contrived. As with the adoption of Norse names, sagas and other features, and the creation of the Norse-Gael culture, Cerball's adoption in Iceland is an example of the contacts between Norse and Gaelic society in the Viking Age
