Eurgain

Saint Eurgain (Eigen) is a saint of the early Church of Wales, regarded in Welsh tradition as the first woman saint among the Britons. The Western calendars commemorate her as founder of Cor Eurgain ("the choir of Eurgain"), later called Llantwit, in the sixth century.

The historical evidence is scanty and doubtful. A manuscript from the Iolo Morganwg collection calls her the daughter of King Caratacus and the wife of Sarllog, lord of Old Sarum, and says she returned from Rome with Caratacus, Saint Cyllin and Saint Ilid and formed a community of twelve, Cor Eurgain, a sign of the early entry of Christianity into Britain. Others believe that a different Eurgain, daughter of Prince Maelgwn Gwynedd and niece of Saint Asaph, lived in Flintshire in the sixth century; the church of Northop (Llaneurgain) bears her name, and her day is 30 June.

She is commemorated on 30 June as a saint of the undivided Church, by the New Calendar.
