Deda mac Sin (Deda, son of Sen) was a prehistoric king of the Érainn of Ireland, possibly of the 1st century BC. Variant forms or spellings include Ded, Dedu, Dedad, Degad, Dega, Dego, Deguth and Daig, with some of these occurring as genitives although usage is entirely unsystematic, besides the rare occurrence of the obvious genitive Dedaid.

He is the eponymous ancestor of the Clanna Dedad,Pokorny 1918Dobbs 1917 and may also have been a King of Munster.

Through his sons Íar mac Dedad and Dáire mac Dedad, Dedu is an ancestor of many famous figures from legendary Ireland, including his "grandsons" (giving or taking a generation) Cú Roí mac Dáire and Eterscél, "great-grandsons" (again) Conaire Mór and Lugaid mac Con Roí, and more distant descendant Conaire Cóem. A third son was Conganchnes mac Dedad.

Through these, Dedu is also an ancestor of several historical peoples of both Ireland and Scotland, including the Dál Riata, Dal Fiatach, Múscraige, Corcu Duibne, and Corcu Baiscind, all said to belong to the Érainn (Iverni), of whom the Clanna Dedad appear to have been a principal royal sept.

The generations preceding Dedu mac Sin in the extant pedigrees appear artificial.Kelleher 1968Dobbs 1917, p. 12 Eventually they lead through Ailill Érann to a descent from Óengus Tuirmech TemrachSin m. Rosin m. Trein/Trer m. Rothrein/Rothrer (m. Rogein) m. Arndil/Arndail m. Maine Mór m. Forgo m. Feradach m. Ailill Érann m. Fiachu Fer-mara m. Óengus Tuirmech Temrach and thus a distant kinship with the Connachta and Uí Néill, whose own pedigree is in fact unreliable before Túathal Techtmar.

A proto-historical sept of the Clanna Dedad are known as the Dáirine,Dobbs 1917, p. 10 descending from Dáire mac Dedad and/or Dáire Doimthech (Sírchrechtach), and are later known as the Corcu Loígde. Alternatively this may be used synonymously, with some confusion created by their identification with the Darini of prehistoric Ulster. In any case, the Darini and Iverni are clearly related.for extensive discussion (in German), see Pokorny 1918

According to the Book of Glendalough (Rawlinson B 502) and Laud 610 pedigrees,ed. Ó Corráin 1997ed. Meyer 1912 a brother of Dedu was Eochaid/Echdach mac Sin, from whom descend the Dál Fiatach of Ulster. But alternatively they descend directly from Cú Roí mac Dáire,Dobbs 1921, pp. 330–1: ... Iatach Find (a quo Dal Fiatach) m. Fuirme m. Conrui m. Dairi Sirchrechtaig m. Deadad m. Sin m. Rosin... and thus from the Clanna Dedad proper. The precise relation of the Dál Fiatach to the Ulaid of the Ulster Cycle, rivals of the Clanna Dedad, is lost to history.

Eoin MacNeill finds the Conaille Muirtheimne to also descend from Dedu mac Sin, from another son Conall Anglonnach,MacNeill 1911, pp. 97–8 believing they are quite mistakenly thought to be Cruthin, as found in later genealogies.

Dui Dallta Dedad was a foster-son of Dedu.

There is also an Ogham of Dedu (Ogam Dedad) found in the Book of Ogams. Over one third of all Irish ogham inscriptions are found in the lands of his descendants the Corcu Duibne.MacNeill 1909, p. 334

The Sil Conairi

{{Main article|Síl Conairi}}

{{See also|Senchus fer n-Alban}}

The Síl Conairi were those septs of the Clanna Dedad descended from Conaire Mór,Dobbs 1917, p. 9 namely the Dál Riata, Múscraige, Corcu Duibne, and Corcu Baiscinn.Byrne, p. 63 The first, presumably settling in far northeastern Ulster in the prehistoric period, would famously go on to found the Kingdom of Scotland. The Royal Family of Scotland, the House of Dunkeld, were described as the "seed of Conaire Mór" as late as the twelfth century.Chadwick, p. 121 Through the House of Dunkeld and Conaire Mór, Dedu mac Sin is an ancestor of the modern British royal family. The last king in the direct male line from the Clanna Dedad and Sil Conairi was Alexander III of Scotland (d. 19 March 1286).

The remaining Síl Conaire would settle and/or remain in Munster, where, although retaining their distinctive identity, they would be overshadowed first by their Dáirine (Corcu Loígde) kinsmen, and later fall under the sovereignty of the Eóganachta. But it appears the Síl Conaire, and especially the Múscraige, actually acted as prominent facilitators for the latter, and this would presumably have been in opposition to the Dáirine.see Byrne, pp. 45, 181 A late and unexpected king of Munster from the Múscraige was Flaithbertach mac Inmainén (d. 944).Byrne, pp. 204, 214

The birth, life, and fall of Conaire Mór are recounted in the epic tale Togail Bruidne Dá Derga.for editions, translations, commentary, and studies, see Togail Bruidne Dá Derga Two distantly related tales of more interest to genealogists are De Síl Chonairi Móir Lucius Gwynn, [https://www.jstor.org/pss/30007892 "De Sil Chonairi Móir"], in Ériu 6 (1912): 130–43. and De Maccaib Conaire.Lucius Gwynn, [https://www.jstor.org/pss/30007893 "De Maccaib Conaire"], in Ériu 6 (1912): 144–53. In these he is confused with his descendant Conaire Cóem.

The Dál Fiatach and Cú Roí

{{Expand section|date=December 2009}}

The descent of the Dál Fiatach princes of Ulster from Dedu mac Sin is less secure, but nonetheless is supported by independent medieval sources (and contradicted by others).

The Dáirine (Corcu Loígde)

{{Expand section|date=December 2009}}

As early as 1849, the great Irish scholar John O'Donovan noted that the pedigree of the Corcu Loígde, the leading historical descendants of the Dáirine, is corrupt for many of the generations preceding the legendary monarch Lugaid Mac Con.O'Donovan, pp. 57, 86
