Princess Saethrith was the daughter of King Anna of East Anglia by his first wife of unknown name. Like her younger half-sisters, Sexburga, Etheldreda, Withburga and Ethelburga, she became a nun. This was after being educated with the latter by St. Fara at the nunnery in Faremoutier-en-Brie in France. She later succeeded her teacher as the second abbess there. She died on 10th January sometime in the late 7th century.
