Ennis is a name of Irish origin, derived from the Irish surname "O'Nuis". The surname O'Nuis comes from the Irish word "nuadha" which means "nude", and it was given to those who were fair-haired or had a pale complexion.
The name Ennis has a long history in Ireland. It is believed that the first person to bear the name was Niall of the Nine Hostages, a High King of Ireland who ruled in the 5th century AD. Niall's descendants went on to become one of the most powerful families in Irish history, and many of them bore the name Ennis.
Today, Ennis is still considered a distinctly Irish name, but it has also gained popularity around the world. It is often used as both a boy's and girl's name, although it may be more commonly associated with males in Ireland. Despite its historic roots, Ennis remains a modern and stylish choice for parents looking for a unique and meaningful name for their child.
