From the experts:
Jarvis, one of the original two-syllable nouveau boys' choices, is a saint's name with a certain retro charm and a nice quirky feel. Though Jarvis peaked in the late 1880s, he is beginning to sound fresh again.
Jarvis Lorry is a character in Dickens's A Tale of Two Cities, and there was another Jarvis in Upton Sinclair's The Jungle. Probably the best known modern Jarvis is British rocker Jarvis Cocker.
