Darragh was on the staff of
St Cyprian's Church in Kimberley from at least 1881, when he contributed an article to the
Quarterly Paper of the Free State Mission. In the early 1880s he placed services on a more regular footing at St Alban's, De Beers (a chapelry then of St Cyprian's), which met in the old De Beers Boardroom. In 1883 he was teaching at the St Cyprian’s Mission School accommodated in a tin house in Clarence Street, Kimberley: Darragh taught "the half-castes who nearly all spoke Dutch". He produced over 70 communicants from among the 200 pupils at the school. Darragh also took classes, with
Canon Gaul, at
St Cyprian's Grammar School: "The idea was to keep the boys’ school in the first place among the Kimberley Schools." == St Mary's, Johannesburg, and the founding of St John's College ==
