Meaning and history
Mildred comes from Old English Mildþryð, meaning "gentle strength" from milde, "gentle," and þryþ, "strength." It was borne by 7th-century abbess Saint Mildred, daughter of the Kentish princess Saint Ermenburga; rare after the Norman Conquest, the name was revived in the 19th century.
Mildred moved from #883 to #968 for girls between 1982 and 1984. Its highest annual birth count came in 1920, with 18,060 births.
