11 8th century Irish people

Abel was a saint and suffragan bishop of Reims in Francia, modern-day France.

Caintigern, or Saint Kentigerna, was a daughter of Cellach Cualann, King of Leinster, and of Caintigern, daughter of Conaing Cuirre. Her feast is listed in the Aberdeen Breviary for 7 January.

Cumianus was an Irish monk who became abbot of San Colombano di Bobbio around 715. He left Ireland as an old man. The intricately carved lid of his sarcophagus, containing a lengthy epitaph, was made by one Master John and commissioned by King Liutprand.

Donnchad mac Domnaill, called Donnchad Midi, was High King of Ireland. His father, Domnall Midi, had been the first Uí Néill High King from the south-central Clann Cholmáin based in modern County Westmeath and western County Meath, Ireland. The reigns of Domnall and his successor, Niall Frossach of the Cenél nEógain, had been relatively peaceful, but Donnchad's rule saw a return to a more expansionist policy directed against Leinster, traditional target of the Uí Néill, and also, for the first time, the great southern kingdom of Munster.

Of the early life of Erkembode, who lived in the late 7th and first half of the 8th centuries, nothing is known. It has been surmised that he was an Irish monk who travelled with several companions to Sithiu, now Saint-Omer in northern France where he lived in the monastery. He was a disciple of the abbot at Sithiu, saint Bertin, himself a disciple of saint Columbanus of Luxeuil, the Celtic abbey in the French Vosges mountains. Later Erkembode was elected by the clergy and people as bishop of Thérouanne, while remaining abbot of his abbey. In later times that abbey of Sithiu became part of the Order of Saint Benedict after the Carolingian reforms of Benedict of Aniane.

Saint Himelin was an Irish or Scottish priest who, returning from a pilgrimage to Rome, fell ill when passing through Vissenaken.

Saint Máel Ruain was founder and abbot-bishop of the monastery of Tallaght. He is often considered to be a leading figure of the monastic 'movement' that has become known to scholarship as the Céli Dé. He is not to be confused with the later namesake Máel Ruain, bishop of Lusca.

Modestus, called the Apostle of Carinthia or Apostle of Carantania, was most probably an Irish monk and the evangeliser of the Carantanians, an Alpine Slavic people settling in the south of present-day Austria and north-eastern Slovenia, who were among the ancestors of present-day Slovenes.

Plechelm, O.S.B., is honoured as a saint in both the Catholic Church and the Old Catholic Church as a patron saint of the Netherlands.

Saint Rumbold was an Irish or Scottish Christian missionary, although his true nationality is not known for certain. He was martyred near Mechelen by two men, whom he had denounced for their evil ways.

Saint Tola is the name of a seventh-century Irish Roman Catholic saint, also referred to as "a good soldier of Christ".
