Quyen is from the Vietnamese Quyên (beautiful bird — specifically the cuckoo or tử quy bird in classical Vietnamese poetry). Quyen in Vietnamese poetic tradition refers to the bird whose call is associated with longing — central to the iconic poetic genre of Vietnamese classical literature. The name appears across Vietnamese feminine naming.
Quyen 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 Quyen reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
