Honor comes directly from the English word — from the Latin honor, meaning "esteem, dignity, public office." English Puritans adopted Honor as a virtue name in the 17th century alongside Faith, Hope, Mercy, and Patience.
Honor entered the U.S. top 1000 in 2008. The actress Honor Blackman (Pussy Galore in Goldfinger) and Jessica Alba's daughter Honor (born 2008) are notable bearers.
Honor 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 Honor reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
