Mildthryth was the daughter of King Merewalh of Magonsaete, a sub-kingdom of Mercia, and Eormenburh (Saint Eormenburga), herself the daughter of King Æthelberht of Kent. Her sisters Milburh (Saint Milburga of Much Wenlock) and Mildgytha (Saint Mildgyth) were considered to be saints. Goscelin, probably relying on a now-lost history of the rulers of the Kingdom of Kent, wrote a hagiography of Mildthryth.
Mildthryth's maternal family had close ties to the Merovingian rulers of Gaul, and Mildthryth is said to have been educated at the prestigious Merovingian royal abbey of Chelles. She entered the abbey of Minster-in-Thanet, which her mother had earlier established, of which she became abbess by 694. Suggesting that ties to Gaul were maintained, number of dedications to Mildthryth exist in the Pas-de-Calais, including at Millam. Mildthryth died at Minster-in-Thanet and was buried there.
