Conall Laeg Breg
Conall Laeg Breg mac Áedo Sláine was a King of Brega from the Síl nÁedo Sláine branch of the southern Ui Neill. He was the son of the high king Áed Sláine mac Diarmato. He ruled from 604-612. He is not called King of Brega in the annals but is second in a poem on the rulers of Síl nÁedo Sláine in the Book of Leinster.
His father had treacherously slain his nephew, Suibne mac Colmáin of the Clann Cholmáin and was then himself slain in battle by Suibne's son Conall Guthbinn setting off a feud among the southern Ui Neill. As part of this feud Conall Laeg Breg was slain in the Battle of Odba by Óengus mac Colmáin of Clann Cholmáin Bicc in 612.
