Before there was Aspen, Denver was the Colorado city name of choice, and we could see it resurfacing as a stylish two-syllable boys' name with the trendy 'er' ending. Its decade of greatest use was the 1920s, when it reached as high as Number 422.

The one noted Denver was actor Denver Pyle, who played Uncle Jesse in Dukes of Hazard. The state capital was named for politician James W. Denver, and others who bore the surname were singer John (born John Deutschendorf), and Bob Denver, the face of Gilligan Island's Gilligan.
