Hronn means a wave — one of the daughters of the sea-god in Norse myth. It carries motion, grace and the oceans rhythm.
Hronn 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 Hronn reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
