Michelle is the French feminine of Michel (Michael) — from the Hebrew Mîkhāʾēl, meaning "who is like God?" — a rhetorical question implying that no one is. The archangel Michael is the chief of the angels in Jewish, Christian, and Islamic traditions.
Michelle peaked at #2 in the U.S. Today it sits in the U.S. top 250. Former First Lady Michelle Obama is one of the most prominent contemporary bearers.
Michelle 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 Michelle reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
