Victoria is the Latin word for "victory" — and the name of the Roman goddess of victory, equivalent to the Greek Nike. The name has been borne by saints, three queens of England, and is currently held by Queen Mary's mother Queen Victoria's namesakes around the world.
Victoria has been continuously in the U.S.
Victoria 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 Victoria reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
