All of these are historically associated with the province of Munster, but according to the early manuscript Rawlinson B 502, Dáire Cerbba was born in Brega, County Meath, and got his epithet from a location there.

While not specifically mentioning a Dáire Cerbba, the Archaic Irish poem Amra Con Roi, and belonging the Ulster Cycle, does state that at one time the family of Ded(ad)/Deguth and Dáire (the family of Cú Roí) had descendants who ruled in Brega to contain the advance of the Ulaid from the north.

(What follows somewhat later is another passage noted for its resemblance to one found in Rawlinson B 502 and in the Book of Ballymote):[17] {folio 98a1} Di raind etir maccu Eilella Flanc Bicc.

Fidach, cuius filius Crimthan Mór mac Fidaigm & Luigtheg for óenleth; Maine Muncháin & Dáre cherbae for leith aili.

The origins of Maine Muncháin/Munchaín or "(of the) Bright/Fine/Beautiful Neck",[18] Dáire Cerbba's replacement in Laud 610 as an ancestor of the Uí Fidgenti, have evaded scholars for generations, but both the epithet and personal name are known from elsewhere in somewhat related traditions.

[20] Margaret Dobbs considers the various ancient people from Eóganacht tradition named Muinemón or Maine to all be equivalent and in different ways associated with the precious metal gold,[21] and in Laud 610 a passage states that "The seventh man from Nuadat was Muinemon.

"[21] while a related passage from the Cóir Anmann tells us that "Munemon first put round throats a golden necklet ... Maine Mor was his name.

"[22] Furthermore, Énna appears to have had, like Dáire Cerbba, his own associations with Brega (Mag Breg), to quote from R. A. S. Macalister's edition of the Lebor Gabála Érenn:[23] Enna Munchain over Mag Breg took hostages of the white Gáedil However, whatever the provenance of the tradition placing some of his career in the midlands, Énna is usually counted an early king of Munster and slayer of Eogan son of Íar mac Degad.

[24] The name Ma(i)ne Munchain itself later appears in the midlands, without any known Eóganachta associations, in a pedigree for the Cenél Fiachach of the Southern Uí Néill found in MS H. 2.

[26] Another Ma(i)ne Munchain appears as an ancestor of Mugain of the Osraige, mother of Áed Sláine of the Southern Uí Néill, in a pedigree giving her a descent from Corc mac Luigdech of the Eóganachta,[27] although this family, the Uí Duach Argetrois, are more usually given a descent from the Corcu Loígde kings of Osraige.

A number of pedigrees preserved in the Book of Leinster appear to resemble one quoted from the Psalter of Cashel in Rawlinson B 502 where Dáire Cerbba is made a son of Maine Munchaín.

[29] Those mentioning or focusing on the Uí Fidgenti omit Maine Munchaín,[30] who in the principle descent scheme variant exemplified in Laud 610 and also found in the Book of Munster,[31] as well as at least suggested in Rawlinson B 502 (depending on whether or not Dáire and Maine may be considered equivalent),[32] completely replaces Dáire Cerbba for the Uí Fidgenti specifically.

Probably the earliest surviving direct mention of Dáire (where assumed Cerbba) in a source from outside the Munster genealogical tradition or any is found in an Old Irish, at least pre-10th century poem, the Maiccni Echach ard a nglé, traditionally attributed to the famous Flann mac Lonáin, Chief Ollam of Ireland.

Various attempts have been made to construct primary descent for some or all of the Eóganachta proper from either the Corcu Loígde or the so-called Érainn altogether,[36] but no consensus has been reached and in fact Crimthann and his family have not actually been the focus of these studies.

Both Eoin MacNeill[37] and T. F. O'Rahilly believed that most, if not all Dáires from Irish myth and legend may derive from the same prehistoric or mythological figure,[38] or have adopted each other's features to such an extent as to all be composites.

In fact the passage gives it the alternative names of "... Ardchluain na Féne and Mucfhalach Mac Daire Ceirbe.

The Mairtine themselves belong only to prehistory and legend, but may be in part ancestral to the later Déisi Tuisceart and famous Dál gCais.
