Camilla comes from the Latin camillus, meaning "young noble attendant at religious ceremonies." In Virgil's Aeneid, Camilla is the virgin warrior queen of the Volsci, raised in the wild.
Camilla is rising in the U.S. (currently top 700) and is the name of the Queen Consort of the UK (Camilla Parker Bowles, born 1947).
Camilla 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 Camilla reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
