Doyne

The name Doyne is an Anglicized form of the Irish surname Ó Dubháin, which means "descendant of Dubhán." Dubhán itself is a diminutive of 'dubh', meaning "dark" or "black." Historically, it was primarily a surname, but like many surnames, it has occasionally been adopted as a given name, particularly in areas with strong Irish heritage.

While traditionally a male surname, its use as a given name is rare and can be found for both genders, contributing to its unisex classification. Its rarity as a given name means it doesn't have a long or well-documented history of gender-specific usage.
