Dennis or Denis is a first or last name from the Greco-Roman name Dionysius, via one of the Christian saints named Dionysius.

The name came from Dionysus, the Greek god of wine, which is sometimes said to be derived from the Greek Dios (Διός, "of Zeus") and Nysos or Nysa (Νῦσα), where the young god was raised. Dionysus (or Dionysos; also known as Bacchus in Roman mythology and associated with the Italic Liber), the Thracian god of wine, represents not only the intoxicating power of wine, but also its social and beneficent influences. He is viewed as the promoter of civilization, a lawgiver, and lover of peace — as well as the patron deity of both agriculture and the theater.

Dionysus is a god of mystery religious rites, such as those practiced in honor of Demeter and Persephone at Eleusis near Athens. In the Thracian mysteries, he wears the "bassaris" or fox-skin, symbolizing new life. (See also Maenads.)

A mediaeval Latinised form of the Anglo-Norman surname Le Denys was Dacus, which correctly meant Dacian, but when the Vikings were about was often used to mean "Danish" or "The Dane". The name became modernised as Denys, then later as Dennis.

O'Neill dynasty

The O'Neill dynasty (Irish: Ó Néill) is a group of families, ultimately all of Irish Gaelic origin, that have held prominent positions and titles in Ireland and elsewhere. As Chiefs of Cenél nEógain, they are historically the most prominent family of the Northern Uí Néill, along with the O'Donnell and O'Doherty. The O'Neills hold that their ancestors were Kings of Ailech during the Early Middle Ages, as descendants of Niall of the Nine Hostages.

A number of their progenitors and members are named as High Kings of Ireland, such as Niall Glúndub (from whom they take their name) and Domnall ua Néill. From 1185 until 1616, the O'Neills were sovereign Kings of Tír Eógain, holding territories in the north of Ireland; particularly around what is today County Tyrone. After their realm was merged with the Kingdom of Ireland and the land was caught up in the Plantation of Ulster, they were involved in a number of significant events, such as Tyrone's Rebellion, the Flight of the Earls, the Irish Rebellion of 1641 and the Irish Confederate Wars.
