Áed's principal church was at Rahugh (Ráith Áeda Meic Bricc) in modern County Westmeath.

Áed mac Bricc's life in the Codex Salmanticensis presents Áed as a peacemaker between Munster and the Uí Néill, and between Mide and Tethbae, befitting his cross-border descent through his mother, Eithne, from the neighbouring Munster people of Múscraige Tíre (north-west County Tipperary).

He frequently visited settlements of holy virgins who received him with the respect due to a man of his position.

[4] Áed's connection to holy women is taken up by Lisa Bitel in Isle of the Saints (1990), by Jim Tschen-Emmons (2002), and in the dissertation by Judyta Szaciłło.

One 8th-century Latin hymn from Lake Constance using this device is addressed to St. Aid "mechprech", who has been identified as Aed Mac Bricc, Bishop of Killare, 6th century.
