Ululani combines the Hawaiian ulu (inspiration, growth) and lani (heaven) — meaning "heavenly inspiration." Queen Ululani was a Hawaiian high chiefess of the 18th century.
Ululani is rare even in Hawaii but distinctive.
Ululani 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 Ululani reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
