Etymology
Koehn is most likely a German surname formed from a shortened or dialectal form of a personal name, commonly linked to Konrad or another first name beginning with the same sound. In German naming practice, such reduced forms often became hereditary surnames. The spelling Koehn reflects the German letter combination "oe," often used for umlauted "ö" in older or anglicized writing.

The surname is found in German-speaking areas and later in communities of German descent abroad, especially in North America.
