Blakely is from the Old English blǣc-lēah — "dark meadow / clearing." A top-200 US baby name since 2014. Sara Blakely (born 1971) — American businesswoman; founder of Spanx (2000) at age 29 with $5,000 in personal savings; in 2012 she became the world's youngest self-made female billionaire (at age 41) on Forbes' list; sold majority stake in Spanx to Blackstone for $1.2 billion valuation in 2021; her business school case study is among the most-cited founder stories in modern American entrepreneurship.

Blakely 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 Blakely reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
