Kimberly is from an Old English place-name — Cyneburg's lēah ("royal one's wood/meadow"). Kimberly Bryant (born 1967) — American electrical engineer; founder of Black Girls Code (2011), the nonprofit that has taught coding to over 30,000 Black girls.
Kimberly 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 Kimberly reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
