I have found some details in Brady's Clerical and Parochial Records (1864), available at:
http://www.corkpastandpresent.ie/history/bradysclericalandparochialrecords/indextoparishes--dioceseofcork/GLENGARIFFE - Glengariffe is a district curacy, formed by deed, dated 31 July, 1861, between the Incumbents of Kilcaskin, in Ross, and Kilmocomoge, in Cork diocese, who pay to the Curate £35 per
an., as an endowment for the new church. The Vicar of Kilcaskin, who pays £20 per an. of above suin, has the first, and the V. Kilmocomoge the second turn of the alternate patronage.
The Earl of Bantry granted, on 13 April, 1861, 1R. 20r. statute measure of land for a new church at Glengariffe.
1860. Divine service is at present celebrated at half-past twelve o'clock, on Sundays, at the hotel, at Glengariffe. Sacrament six times in the year; average of communicants, 5. The Curate is Rev. Vincent Lamb, A.B., who was, on 23 January, 1855, licensed to this curacy at £75 per an. on the nomination of the V. Kilmocomoge and the V. Kilcaskin jointly.
A new church, on the site granted in 1861, by Lord Bantry, is now (March, 1863), nearly finished. The designs for it were furnished by the Ecclesiastical Commissioners, and were slightly
modified by the Archdeacon of Cork (S. M. KYLE), who originated the idea of placing a church in this romantic locality, and who collected the greater portion of the funds.
