Kings and Dynasties of Mide and Brega
The Southern Uí Néill
[not to be confused with O'Neill] were among the leading dynasties in the "middle
kingdom" of Midhe
from the 5th century up to the arrival of the Normans in the 12th century. Their main territories included the ancient areas about Mide
and the plain of Brega
, which included the modern counties of Meath and
Westmeath, as well as portions of counties Longford, Offaly, Louth, Dublin and Kildare. Prior to the arrival of the sons of Niall of the Nine Hostages in the 5th century, the areas of Mide and Brega were ruled under dynasties which included the Laigin, as the area has been speculated to be previously a part of the kingdom of ancient Leinster. Of the sons and grandsons of Niall of the Nine Hostages who conquered territory in this area, there included Lóegaire
, ancestor of Cenel Lóigaire
; Conall Cremthann
, ancestor of Clan Cholmáin
(Mide) and Sil Áeda Sláine
, ancestor of Cenel Cairpri
Laigen and Cairpri Gabra; Fiachu
, ancestor of Cinel Fiachach
and dynast of Fir Cell
; and Maine
, dynast of Tethba
describes the boundary of Brega as: "its bounds seem Belach dúin (alias Castlekieran in the barony of Kells Upper) and the sea; the Boyne and Cassán (at Annagassan, southeast of Castlebellingham)."
