Biography

Dauí Tenga Uma is listed in the genealogies as a great-great-great grandson of Brión, the eponymous founder of his dynasty. He is specifically stated to be the ancestor of the Uí Briúin Seóla branch. Francis Byrne believes him to be a duplicate of his supposed great-great grandfather, Dauí Galach, that the early Uí Briúin genealogies are fabrications and that these two were the same person. Dauí succeeded Ailill Molt of the Ui Fiachrach as king.
Keating mentions two marital relations of his family:

his daughter Duinseach ingen Duach married the high-king Muirchertach mac Ercae of the Cenel nEogain and was mother of his sons Domnall and Fergus;
his granddaughter Mugain ingen Cú Charainn was married to the high-king Diarmait mac Cerbaill of the southern Ui Neill and mother of the high-king Áed Sláine.

In 500 Daui was defeated and slain at the Battle of Segsa by his own son-in-law Muirchertach mac Ercae. The annals record that the war was caused by his daughter Duinseach.
