Brennan is an Irish surname which is an anglicised form of two different Irish-language surnames: Ó Braonáin and Ó Branáin. Historically, one source of the surname was the prominent clan Ua Braonáin (O'Brennan) of Uí Duach (Idough) in Osraige who were a junior Dál Birn sept stemming from a younger son of Cerball mac Dúnlainge (d.888). Recent surname evaluations highlighted the geographic consistency of this lineage in the barony of Idough. However, based on the ultimate authority of Dubhaltach Mac Fhirbhisigh they are out of Ui Dhuinn (O’Dunn) and, therefore, an Uí Failghi tribe, not Osraige. While it is clearly apparent that O’Hart's pedigree is erroneous, it is suggested that Ó Cléirigh probably became confused while transcribing from Mac Fhirbhisigh. This is echoed by the modern scholar, Bart Jaski.
Donald is a masculine given name derived from the Gaelic name Dòmhnall. This comes from the Proto-Celtic *Dumno-ualos. The final -d in Donald is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers, and partly associated with the spelling of similar-sounding Germanic names, such as Ronald. A short form of Donald is Don, and pet forms of Donald include Donnie and Donny. The feminine given name Donella is derived from Donald.
