Liliana is the Latinate elaboration of Lily — from the Latin lilium, the lily flower.
Liliana is widely used across Italy, Spain, Portugal, Romania, and Latin America. In the U.S. it sits in the top 130 and has been climbing. The character Liliana Vess in Magic: The Gathering has brought it new gaming-culture visibility.
Liliana 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 Liliana reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
