The name "Dan" is derived through a truncation-suffix method from the full Slavic name "
Bohdan" or from one of the calendar names such as "
Danylo," "Yordan," or the Bulgarian name "Danyo." Sources from the year 1404 record: "...Dragomir and his brother Dan..." - the town of Sighet. A notable bearer of this name in 1649 was the Cossack Dan Pakoshenko from the
Bratslav regiment.
