Lorelei is the name of the famous rock cliff on the river Rhine in Germany — and of the legendary siren who supposedly sat atop the cliff, combing her hair, and lured sailors to their deaths on the rocks below. The name comes from lureln (to murmur) and ley (rock).
Today Lorelei sits in the U.S. top 500 and is rising.
Lorelei 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 Lorelei reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
