Yvette is the French feminine of Yves — from the Old Germanic iv (yew tree, the wood traditionally used for archery bows in medieval Europe). Yvette Mimieux (1942-2022) — American actress; star of The Time Machine (1960, opposite Rod Taylor — one of the first major MGM sci-fi films); Where the Boys Are (1960), Light in the Piazza (1962), The Black Hole (1979 Disney).
Yvette 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 Yvette reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
