Murrough Ua Cellaigh
Rebellion apparently began again when during 1183-1186, further warfare broke out among the Uí Conchobair, which resulted in Ruaidrí Ua Conchobair been forced to resign the kingship in favor of his son, Conchobar Máenmaige Ua Conchobhair.
Conchobar Máenmaige swiftly dealt with Ua Cellaig, whose territory compromised the largest single lordship within the kingdom. The annals record his death at the hands of Ua Conchobair, who was assassinated in 1189.
This may simply mean that Murrough's family subsequently lost status and were no longer regarded a nobles, as his son, Aodh, was king when he died in 1206.
