| Background: Maher, also written Meagher, is in Irish O Meachair, derived from the word meachar, meaning hospitable - Maher is a word of two syllables, not pronounced Marr. Of the same stock as the O'Carrolls of Ely it belongs to the barony of Ikerrin in Co. Tipperary - in fact fifty per cent of the eight thousand people of the name come from Co. Tipperary. Maher territory was near Roscrea, at the foot of the famous Devil's Bit Mountain and , unlike some Gaelic septs, they were not ousted by Norman invaders but remained in possession side by side with the Ormond Butlers. Though this is a genuine Gaelic O name it is rarely, if ever, met with in its English form with the prefix.
Variations: O'Meagher, Maher, O'Maher, Mahir, Meagher.
