Nevan
Nevan was a saint in Irish folklore whose feast day was reputedly marked in mid-September. In Seathrún Céitinn's General History of Ireland, Naomhán is described as the "son of Maolciarain, primate of Ireland".
Sometimes associated with the surname MacNiven, the name is also sometimes used as a given name for boys.
With a different origin, Nevan is also a popular Islamic name found throughout North Africa, Arabia, and the Indian subcontinent.
