Very little is known of her life; however, she is known to history mainly through the hagiography of the Secgan Manuscript, and the Life of St Hildelith written in 1087 by the Medieval Benedictine hagiographical writer Goscelin. She was abbess of the nunnery at Barking in England, succeeding the role from the abbey's founder, Æthelburh of Barking. It is not known who replaced her as the next known abbess is Wulfhild of Norway, three centuries later and just prior to the Norman Invasion. Hildelith was unique in that under her control the abbey acted as a double monastery.
