While browsing through a book called Pittsburgh and Pennsylvania Genealogies (Fragmenta genealogica hearldica), I came across this valuable tidbit detailing the lineage of the Irish nation back to Adam and Eve, the progenitors of all people.
The list titled "The Stem of the Irish Nation from Adam down to Milesius of Spain, Showing the Descent of O'Leary", begins at Creation, generation 1, as follows:
Pheniusa Farsaidh [Fenius Farsa]
Beouman (King of Scythia)
Ogaman (King of Scythia)
Tait (King of Scythia)

Nuadhad (King of Galacia)
Alladh (King of Galacia)
Arcadh (King of Galacia)

The book is loaded with facts about the Irish and other interesting information.
