"Amongst the clergy present were the very rev. William Delany, S.J., L.L.D.; the rt rev. Gerald Molloy, D.D.; the rev. P.J. Kavanagh, C.S.Sp.;" (U12.928)
C.S.Sp. stands for Congregatio Sancti Spiritus = the Congregation of the Holy Spirit, aka Spiritans. It was founded in Paris by Claude-François Poullart des Places (1703). The purpose of the congregation was to minister to the poor, and to provide chaplains in hospitals, prisons, and schools. It quickly grew a missionary role. The Spiritans came to Ireland in 1859 and focused on education. They founded Blackrock College (1860), Rockwell College in Cashel (1864), and St Mary's College in Rathmines (1890). The back of this Dublin CDV identifies Rev. P. Kavanagh - the same one?
