Ruaidhri may have succeeded by killing his brother, Conchubhar; the
Annals of Ulster,
sub anno 1186, record that
"Conchubhar Ua Flaithbertaigh was killed by Ruaidhri Ua Flaithbertaigh, by his own brother, in Ara." Ruadhri was taken prisoner by King
Cathal Crobhdearg Ua Conchobair of Connaught in unknown circumstances in 1197. There is no further record of him. ==See also==
