Dál gCais
The Dalcassians ( ) are a Gaelic Irish clan, generally accepted by contemporary scholarship as being a branch of the Déisi Muman, that became very powerful in Ireland during the 10th century. Their genealogies claimed descent from Tál Cas. Their known ancestors are the subject of The Expulsion of the Déisi tale and one branch of their blood-line went on to rule the petty kingdom of Dyfed in Wales during the 4th century; probably in alliance with the Roman Emperor Magnus Maximus.
Déisi
The Déisi were a social class in Ireland between the ancient and early medieval period. The various peoples listed under the heading déis shared a similar status in Gaelic Ireland, and had little or no actual kinship, though they were often thought of as genetically related. During the era of Roman rule in Britain, many members of the Déisi were recorded as settling in western British coastal areas (especially the areas known later as Wales, Cornwall and Devon).

Flannán
Flannán mac Toirrdelbaig (; ) was an Irish saint who lived in the 7th century and was the son of an Irish chieftain, Toirdhealbhach of Dál gCais. He entered Mo Lua's monastery at Killaloe, where it is believed he became an Abbot. He is remembered as a great preacher. He made a pilgrimage to Rome where Pope John IV consecrated him as the first Bishop of Killaloe, of which he is the Patron Saint. He also preached in the Hebrides. His feast day is 18 December.
