At the
Synod of Rathbreasail in 1111,
Tuam was named as the seat of a
diocese corresponding roughly with the
diocese of Elphin, whilst
Cong was chosen as the seat of a diocese corresponding with the later archdiocese of Tuam in west
Connacht. There is no record of any bishops of Cong, and no bishop was given the title "bishop of Tuam" in the Irish annals before 1152. However the annals recorded some "archbishops/bishops of Connacht" such as Cathasach Ua Conaill (died 1117),
Domhnall Ua Dubhthaigh (1117–1136),
Muireadhach Ua Dubhthaigh (1136–1150) – the latter was succeeded by
Áed Ua hOissín. At the
Synod of Kells in 1152, the archdiocese of Tuam was established with six suffragan dioceses. The current archbishop is the Most Reverend
Francis Duffy who was announced as the new archbishop of Tuam by the
Holy See on 10 November 2021 and subsequently installed on 9 January 2022. The archbishop's residence is the Archbishop's House, Tuam, County Galway, Ireland. ==Pre-Reformation archbishops==
