The name "Billko" is an old Ukrainian masculine name that is used in everyday life. This name was given to boys with snowy white hair or light skin. The word "Billko" is derived from the adjective "bil" (meaning "blond") with the suffix "-ko." Historical references to the name date back to 1552 when Billko Dèbritskiy appears in documents from Vinnytsia. Besides Ukrainians, the name "Billko" (also the variant "Billchan") is mentioned among Serbs in the 14th century.
