Koen

Koen (Dutch pronunciation: [ˈkun] ) is a Dutch language given name and surname, popular in the Netherlands and Flanders. Although the earliest direct attestation comes from Oudenaarde, East Flanders in 1272, it is known to have been derived from the Proto-Germanic name *kōnja-, meaning "brave". The given name is often an abbreviation of Koenraad. Kōen is a Romanization of an unrelated Japanese family name.
