The eastern and northern part of county Sligo, including Sligo town, belonged to the united Church of Ireland diocese of Kilmore, Elphin and Ardagh.
The Rt Rev Alfred George Elliott (1828–1915) was Bishop of this diocese from 1897 until his death in 1915. He had been educated at Trinity College, Dublin, he was ordained in 1858 and his first post was a curacy at Bailieborough.
At the 1913 diocesan synod the Bishop attacked home rule saying "Our efforts to avert the danger have not succeeded. Its approach seems now so near that its shadow is already upon us. Unless it pleases heaven to interfere on our behalf, I see no possibility of averting the action of our rulers, Utopian in its conception, and bound to be calamitous in its consequence."
He then went on to speak at length of the suffering of loyalists under "Home Rule" during the reign of James II. This address led to much negative comment and criticism of the Bishop in the nationalist press.
The rest of Sligo was part of the diocese of Tuam, Killala and Achonry. John Plunket, born in Bray and educated at Harrow and Cambridge, was elected bishop in April 1913. His statement that ‘happy relations’ existed between his people and their Catholic neighbours was given prominence in thee nationalist press and his attitude was contrasted with that of Bishop Elliott.
The Rt. Rev. William Bedell, D.D. (1571–1642), served as Lord Bishop of Kilmore. He was born in Essex and educated at Cambridge. During the Irish Rebellion of 1641 he was captured and tortured by the rebels. After being released he died as a result of his ill-treatement.
