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.
Queen Victoria (1819-1901), who reigned for 63 years, gave the name its lasting prominence. Victoria has been continuously in the U.S. top 100 for 80 years and currently sits at #25 — one of the few classical names never to leave the top tier.
Victoria reduces to five — the number of decisive triumph.
