Egwine was a 6th-century Celtic princess and saint, who is a patron saint of the village of Llanigon, east of Hay-on-Wye, in the Wye Valley of Wales.
Very little is known of her life. She was the sister of saints Cadoc,[1] Maches and Cyndr,[2] who all built churches in the same area.
She was also the daughter of Gwladys,[3] and granddaughter of king Brychan of Brycheiniog.
