Saint Mildgyth (d. c. 676) was the Anglo-Saxon abbess, sister of Saints Mildred and Mildburh — youngest of the three holy sisters, daughters of the Kentish princess Eormenburg.
Featured in the Mildrith Legend.
Mildgyth does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Mildgyth reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
