Ualgarg Mór Ó Ruairc

Ualgarg Mór Ó Ruairc (died 1346) was King of West Breifne from 1316 until his death in 1346. His long and influential reign ensured that his descendants would rule West Breifne for the rest of its history, 250 years after his death. The rival branches of the O'Rourke sept which emerged in the 15th century - the Carrigallen O'Rourkes, Dromahair O'Rourkes and Carha O'Rourkes - all trace the lineage back to Ualgarg Mór.
