Helene is from the Greek Ἑλένη (Helénē — torch, light, bright one) — from Greek helē (sun-ray) or selas (light). Helene is one of the Greek feminine names — central to traditional Greek epic heritage.
Helene 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 Helene reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
