Eochaidh Muighmeadhon, had twenty-four sons, who were contemporaries of Laoghaire, son of Niall. Their leader was Eichen, the youngest was Duach Galach who later became King. [1] Duach Galach (Duach the Valiant) was the first Christian King of Connaught. Of his many brothers, Connell Orison, Arca-Dearg and Aongus are known to have left descendants. [2]
We read in The History of Ireland by Geoffrey Keating, that a descendant Duach Galach, Duach Teangumha, son of Fearghus, son of Muireadhach Mal, son of Eoghan Sreibh, son of Duach Galach, son of Brian, son of Eochaidh Muighmeadhon, "was king of Connaught seven years at this time, and he fell by Eochaidh Tiormcharna". [3]
The date for the death of Duach Mac Briain in 425 is discussed by John B. Bury in his book, The Life of St. Patrick and His Place in History (appendix p: 365).
