Biography.
A grandson of Gadhra Mór mac Dundach and a son of Madudan mac Gadhra Mór, Madudan Reamhar was the first bearer of the surname Madden, a family originally from east County Galway.
He died of a pestilence which caused "a great mortality of the men of Ireland" in 1095. Following his death, Gillafin Mac Coulahan (one of his descendants was Arthur Colahan) became ruler but was killed in 1101 by Madudan's son, Diarmaid Ua Madadhan.
His nickname "reamhar" meant large or fat.
