Catherine FitzCharles

Catherine FitzCharles (1658–1759) was the illegitimate daughter of Charles II of England and his mistress Catherine Pegge.^[1] Her older brother by one year, Charles FitzCharles, was made the 1st Earl of Plymouth by his father.^[2] Little is known about Catherine's life, but she is thought to have become a Benedictine nun at Dunkirk Abbey [fr] in Dunkirk, France, like many other highborn Englishwomen during the reign of Charles II.^[3] She is believed to have resided there under the religious name, Sister Ophelia, until her death in 1759, aged 101.^[4] However, the small amount of information available about her has led some to conclude that she died in infancy or early childhood instead.^[5]
