Eochaid mac Óengusa
Eochaid mac Óengusa was a King of Munster from the ruling Eoganachta dynasty. He was the son of Óengus mac Nad Froích, the first Christian king of Munster.
The chronology of the 6th century Munster kings is confusing in the sources. According to the Laud Synchronisms, he succeeded his father as king and was a contemporary of the high king Lugaid mac Lóegairi which would place the start of his reign before 507. However, in the Book of Leinster, he succeeded his brother Feidlimid mac Óengusa.
He had two sons born on the same night: Crimthann Srem, ancestor of the Glendamnach sept of Eoganachta and another Crimthann by a woman named Dearcon, ancestor of the Arithir Cliach sept of Eoganachta. it is possible that the creation of two separate Crimthanns was an invention of the genealogists. He was succeeded by his son Crimthann Srem mac Echado.
