Mandukhai Khatun (1449-c. 1510) — "Manduhai the Wise" — was the Mongol Empress who reunified the fractured Mongol nation in the late 15th century.
Mandukhai 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 Mandukhai reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
