The cathedral is dedicated to St. Daniel, its first bishop, and the chapter consists of a dean, treasurer, precentor, two archdeacons, five canons, and two minor canons. The diocese comprises Anglesea, and parts of Caernarvonshire, Denbigh, Montgomery, and Merionethshire, containing one hundred and seventy parishes, of which thirty-seven are impropriated. The present (1889) incumbent is James Colquhoun Campbell, D.D., consecrated in 1859.
