Eveleen is either a diminutive of Eve or a variant of Evelyn. Evelyn is a matronymic English surname derived from the medieval girl's name Aveline, which is of Norman origin and represents a diminutive form of Ava. Since the 17th century, it has also been used as a given name. In some cases, the given name may represent an anglicized form of the Irish names Aibhilín and Éibhleann, with the latter deriving from the Old Irish óiph, meaning 'beauty, radiance'.
