Stephanos of Byzantium - Ethnika
Kromna: a city of Paphlagonia, now Amastris, as has been said. Some, however, say it is a district of Amastris. The ethnonym is 'Kromnites' and 'Kromnaios' and 'Kromnaieus'. There is also a city of the Peloponnese, in the masculine and feminine, and in the singular and plural, named after Kromnos son of Lykaon.
