Cheryl is a 20th-century American blend of Cherie + Beryl — from the French cher ("dear") + the Greek beryllos (the gemstone beryl). Cheryl Strayed (born 1968) — American memoirist; Wild: From Lost to Found on the Pacific Crest Trail (2012) spent 7+ weeks at #1 on the New York Times bestseller list and was adapted to a 2014 film starring Reese Witherspoon.
Cheryl 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 Cheryl reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
