Ambrose Ó Madadhan, first Prior of Portumna Priory.
The Dominican Order had been established in Portumna before the 17th century, its first patrons apparently the Ó Madadhan lords of Síol Anmchadha.
He was possibly closely related to Domhnall Ó Madadhan, the last Chief of Síol Anmchadha.
With the Cromwellian conquest of Ireland in 1652, the community were either expelled, exiled or killed.
