Stacey is a diminutive of Anastasia — from the Greek anastasis ("resurrection, rising up"). Nominated for the 2021 Nobel Peace Prize.
Stacey 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 Stacey reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
