Servilia is the Latin feminine of the gens Servilia. Servilia Caepionis (c. 100-42 BCE) was the Roman noblewoman who was Julius Caesar's longtime mistress and the mother of Marcus Junius Brutus — the assassin of her own lover.
Servilia is rare but iconic in Roman history.
Servilia 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 Servilia reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
