St. Euphrasia was the only child of noble Christian parents serving the court of the Christian Emperor Theodosius I, their relative.

After her birth her parents vowed to remain celibate in order to commit their lives fully to prayer and penance.  Her father died soon after, and Euphrasia moved with her mother to Egypt near a large monastery of nuns.  At the age of seven Euphrasia vowed her virginity to Christ and desired to join the monastery.  Her mother gladly presented her to the abbess, and then died soon after.  When the Emperor heard of her mother's death, he sought out Euphrasia for an arranged marriage.  Euphrasia denied the offer due to the vow, and requested that her large estate be sold with the money given to the poor, and all her slaves freed.  The Emperor was greatly pleased with her chosen course in life, and did all that she asked. 

As a nun Euphrasia did great penances.  In order to resist temptations to sin, she would perform difficult manual labor, often lifting heavy stones and moving them from one place to another for days on end, and other such drudgery.  She was known to perform miracles both before and after her death at the age of thirty.
