Juliana is the Latin feminine of Julian — from Iulius (the Roman gens name) — and a name shared by Roman empresses and modern queens. A top-200 US baby name since 2003. Juliana Hatfield (born 1967) — American alternative-rock singer-songwriter; Become What You Are (1993). Juliana Daniell (1903-1989) — Brazilian actress. Juliana Marins — Brazilian actress. Juliana Margulies — Julianna Margulies (slightly different spelling). Juliana of Lazarevo — Russian Orthodox saint (1604).
Juliana 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 Juliana reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
