ORIGIN & HISTORY

About the name

As a place-name-derived surname, Colby traces to Old Norse Koli (a byname meaning "coal" or "dark/swarthy") combined with býr ("farm, settlement") — so, approximately "Koli's farm" or "the dark-haired one's settlement." This is the surname's own etymology; the given name is a transferred use of that surname rather than a name independently coined for its meaning.

  1. Documented roots: Transferred use of the English surname Colby, itself from place names combining Old Norse Koli (a byname meaning "coal" or "dark-haired") and býr ("farm, settlement").
