This family is descended from the same ancestor as "Casey" No. 1. These O'Caseys were lords of Saithne, in the County of Dublin (a territory which was co-extensive with the barony of Balrothery, West), of which they were dispossessed by DeLacy at the time of the Anglo-Norman Invasion:

O'er Saithne of Spears (here Delvan rolls his flood),

O'Casey rules, whose sword is stained with blood.—O'Dugan.

The O'Caseys were also styled lords of Magh Breagh or Bregia, which comprised five of the thirteen Triocha Ceads of the ancient principality of Meath. Saithne was a subdivision of Bregia of which the O'Caseys assumed sovereign authority. Bregia extended from Dublin City to Beallach Brec, west of Kells, and from the Hill of Howth, to the mountain of Fuad on the south of Ulster. We read in the Irish Annals, that:

A.D. 1018. Oisin O'Casey, lord of Saithne and Fingal, was slain.
1023. Ainbeth, lord of Saithne, was slain.
1049. Torloch O'Casey was put to death.
