Uada was the son of Muirgheas Ua Cú Ceannainn, who appears to be identical with the man of that name who died in 1105.
Dubhaltach Mac Fhirbhisigh records of him "Uada son of Muirgheas took the full kingship of Uí Díarmata and he was a man of great fame in terms of honour, dexterity and appearance.
The next recorded king was Cú Ceanain Ó Con Ceanainn, who died in 1224, but his relationship to Uada is uncertain.
Mac Fhirbhisigh gives the pedigree of his descendant, Domhnallán Ó Con Ceanainn as follows, tracing him back to Uada.
Uda was a contemporary, and subject of, King of Connacht Ruaidrí Ua Conchobair, who was also High-King of Ireland.
