Daciana is the Romanian feminine name from Dacia — the ancient Roman province (modern Romania). Meaning "from Dacia" or "Dacian woman."
Daciana Sârbu (born 1977) is the Romanian politician.
Daciana 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 Daciana reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
