Alice comes from the Old French Aalis, itself from the Old Germanic Adalheidis — meaning "noble kind" or "of noble birth." The same root gives Adelaide, Adelina, and Heidi.
Alice has stayed in the U.S. top 200 for over a century and is currently at #58, climbing — a classical name that never quite leaves.
Alice 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 Alice reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
