Raelynn is a modern American compound name combining Rae (an English diminutive of Rachel or short for Ray) with -lyn(n) ("waterfall, ravine"). "Lonely Call" (2017) and "Bra" (2018). Performed at the 2017 CMT Music Awards. Raelynn Tappel — American beauty pageant winner.
Raelynn 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 Raelynn reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
