Eachmarcach is a personal name meaning 'horse-rider'. It is the origin of the surname Mac Eachmharcaigh, which can be anglicised Cafferkey or McCafferty and is a common surname in Mayo [De Bhulbh]. It would seem that this is the most likely origin of Knockaffertagh, though an Irish form for the name has not been found to support this. The t in Knockaffertagh is not a problem as the anglicisation McCafferty shows that such a pronunciation of Eachmarcach is possible. The hill is named Ummeraufferty on William Bald's map of Co. Mayo (1830), which appears to be a similar name with Ir. iomaire, 'ridge' as the first element instead of cnoc.
