Speranza is from the Italian Speranza — from the Latin spes (hope). Speranza is one of the three theological virtues in Catholic tradition — alongside Fede (faith) and Carità (charity) — central to St. Paul's 1 Corinthians 13:13. Lady Jane Wilde (Jane Francesca Agnes Elgee, 1821-1896) — Irish poet who wrote under the pen name Speranza — was the Irish nationalist poet of the Young Ireland movement and the mother of Oscar Wilde. Italian-Maltese-Spanish feminine name across modern Catholic communities.
Speranza 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 Speranza reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
