History & Origin

Colby derives from an Old Norse place-name found in England, composed of Koli (an Old Norse byname meaning 'charcoal' or 'coal-black') and by ('farm' or 'village'). Multiple English villages bear this name, and it became a common English and American surname. As a given name it follows the well-established American pattern of converting place-names and surnames to first names.

Colby became popular as a given name in the United States in the 1980s and 1990s, benefiting from the Western-flavored surname-name trend. It peaked in the early 2000s and has remained in steady use, ranking comfortably in the U.S. top 300 boys' names. The name carries an approachable, outdoorsy American character.

Did you know? Colby cheese — the mild, orange American cheese — was invented in 1885 in Colby, Wisconsin, a town named after Jesse Colby who settled there in 1845. The town, the cheese, and the given name all trace to the same Norse settlement-word, making Colby a name literally consumed by millions every day.
