Answer 2

According to Wikipedia, the Brontë family can be traced to the Irish clan mac Aedh Ó Proinntigh, which literally means 'son of Aedh, grandson of Proinnteach'. Aedh is a male name derived from Aodh, meaning "fire". "Proinnteach" ("the bestower") originated as a byname for a generous person. Literally meaning "banquet hall", the word is composed of the Gaelic proinn ("banquet") (a cognate of the Latin prandium["meal"]) and teach ("house", "hall"). Ó Proinntighwas earlier anglicised as Prunty and sometimes Brunty. At some point, the father of the sisters, Patrick Brontë (born Brunty), conceived of the alternate spelling with the diaeresis over the terminal "e" to indicate that the name is of two syllables.
