Quick answer
Ninian is a boy name.
Meaning and history
This name comes from the name of a 5th-century British saint, known as the Apostle to the Picts, who was apparently responsible for many miracles and cures. He first appears briefly in the 8th-century Latin writings of the historian Bede, though his name is only written in the ablative case Nynia. This may represent a Brythonic name * Ninniau.
