Minerva is the Roman goddess of wisdom, strategic warfare, the arts, and crafts — equivalent to the Greek Athena. The name derives from a root meaning "mind" or "intellect."
Minerva peaked at #382 in the U.S. in 1881. Today the name is returning slowly — propelled in part by Minerva McGonagall in Harry Potter.
Minerva 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 Minerva reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
