Pompeia is the Latin feminine of Pompey. Pompeia (c. 86-after 35 BCE) was the granddaughter of Sulla and second wife of Julius Caesar — divorced by him after the Bona Dea scandal, even though she was innocent.
Featured in Roman historical narratives.
Pompeia 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 Pompeia reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
