Region of originIreland

Brennan (/ˈbrɛnən/)[1] is an Irish surname which is an anglicised form of two different Irish-language surnames: Ó Braonáin and Ó Branáin (or Mac Branáin).[2][3][4] Historically, one source of the surname was the prominent clan Ua Braonáin (O'Brennan) of Uí Duach (Idough)[5] in Osraige who were a junior Dál Birn sept stemming from a younger son of Cerball mac Dúnlainge (d. 888).[6] Recent surname evaluations highlighted the geographic consistency of this lineage in the barony of Idough.[7][8] However, based on the ultimate authority of Dubhaltach Mac Fhirbhisigh they are out of Ui Dhuinn (O’Dunn),[9] and, therefore, an Uí Failghi tribe, not Osraige. While it is clearly apparent John O’Hart's given pedigree is erroneous, it is suggested Ó Cléirigh probably became confused while transcribing from Mac Fhirbhisigh.[10] This view is echoed by modern scholar Bart Jaski.[11]

The Irish surname Ó Braonáin, means "descendant of Braonán". The personal name Braonán is derived from a word which means "moisture", "drop". The Irish surname Ó Branáin, means "descendant of Branán". The personal name Branán means "little raven".[12] Brennan is also a given name.
