Honor is a somewhat more straight-laced virtue name than Hope or Grace, placing a high standard on any girl carrying it, but it's a goal worth setting. By choosing Honor for her daughter, Jessica Alba brought it very much into the modern world. 
 
Honor has become popular as a nonbinary name, given to nearly equal numbers of girls and boys but not ranking in the Top 1000 for either.
 
Probably the best known bearer is British actress Honor Blackman, remembered for her roles in The Avengers and the James Bond Goldfinger.

Thackeray and Honoria Glossop, a character in the Jeeves stories by P. G. Wodehouse.
