Patrizia is the Italian form of Patricia — from the Latin patricius, meaning "of the noble class" or "patrician."
Patrizia Reggiani (born 1948), known as the "Black Widow" of Italy, is the convicted mastermind of the 1995 murder of Maurizio Gucci — depicted in Ridley Scott's House of Gucci (2021).
Patrizia 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 Patrizia reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
