Statilia is the Latin feminine of Statilius. Statilia Messalina (c. 35-c. 80 CE) was the cultured Roman noblewoman and Nero's third and final wife — after Nero murdered her husband Atticus Vestinus to marry her.
Featured in Suetonius's Life of Nero.
Statilia 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 Statilia reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
