Probably a Welsh form of *Ninniau (see Ninian). This form is used for Nennius in Brut y Brenhinedd [1], the Middle Welsh translation of the 12th-century Latin chronicles of Geoffrey of Monmouth. The name also appears in the Welsh tale Culhwch and Olwen belonging to a man who is transformed into an ox [2].
