He held the curacy of St. Matthias, Dublin, for seven months in 1855, and was afterwards presented by his grandfather, Mr. Heard, to the vicarage of Rincurran. Here his earnest preaching attracted large congregations, and he soon had to enlarge the church. Among other works commenced and carried out by him with great success were a special class for servants and the chaplaincy to the garrison at Charles Fort. On 11 January 1867 he resigned Rincurran, was for a short time rector of Ballymoney, co. Cork, and then became rector of Stackallen, County Meath, and private chaplain to his friend and diocesan, Samuel Butcher. In August 1867 he left Stackallen for the vicarage of St. Matthias, Dublin. In the metropolis his fame crowded his church, where he preached morning and evening every Sunday, and when it was found necessary to rebuild his church, he preached in the large concert hall in the exhibition palace to congregations which averaged upwards of three thousand persons. After a last service held in this place on 31 July 1870, he took possession of his new church. His influence in Dublin was great, not only among adults, but with students and young ladies. As soon as the new constitution of the ‘disestablished’ church came into action, Daunt was elected to the responsible office of diocesan nominator. He was also chosen the representative canon in St. Patrick's Cathedral for the united diocese of Dublin and Glendalough, and was named a member of the committee connected with the general synod called the ‘revision committee’, where he sided with the ‘party of movement’; but his influence was largely exercised in acting as a peacemaker. The incessant labour in Dublin was now telling on Daunt's health, and his old friend John Gregg, Bishop of Cork, Cloyne and Ross, offered him in 1875 the deanery of Cork and the rectory of Saint Finbarre's Cathedral, which he accepted. But his health was broken. He died at St. Anne's hydropathic establishment at Blarney on 17 June 1878, and was buried in Mount Jerome Cemetery, Dublin, on 21 June. He married, 24 February 1863, Katherine Mary, daughter of the Rev. John Leslie, rector of Castlemartyr.
