Hard as it may be for many American parents to believe, this Norman name is enjoying a big style revival in England--it's in the Top 50 there--along with similar choices like Stanley and Arthur. And it just could happen here, what with the many other Har-starting names trending for both girls and boys.
Harvey did have a respectable run as a Top 100 name in the U.S. in the late nineteenth and early decades of the twentieth century, after which it began to get a bit of a nerdy rep.
Harvey, which was brought to England by the Normans and is a version of the French name Herve, does have some noteworthy references, such as a blind sixth century saint who was said to be a monk and minstrel able to talk to animals. Later Harveys include industrialist Firestone, martyred San Francisco public figure Milk, comics legend Pekar, and performers Keitel, Korman and Fierstein. Harvey was the name of an invisible man-sized rabbit who could only be seen by Jimmy Stewart's Elwood P. Dowd in a popular 1950 movie, and was the name of the main character in Rudyard Kipling's novel Captains Courageous.
