Gwansun (관순) — "crown obedience." Yu Gwan-sun (1902-1920) was the Korean independence activist who at just 16 led the Aunae Marketplace protest during the March 1st Movement of 1919 against Japanese colonial rule. The "Korean Joan of Arc" — her statue stands at her birthplace; her face appears on commemorative stamps.
Subject of the 2019 Korean film A Resistance.
Gwansun 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 Gwansun reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
