Anne is the medieval French form of the Hebrew Hannah ("grace, favor"). Anne Boleyn (Henry VIII's second wife, beheaded), Anne of Austria (regent of France), Anne Sexton (Pulitzer-winning American poet), Anne Carson (Canadian classicist-poet) — the name appears at every node of Western cultural history.
Subject of countless biographies, films, and adaptations.
Anne 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 Anne reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
