MALLEY Family History
Recorded in many forms including Malley, Mailey, Meally, Melley, Melly, Melia, all found with or without the prefix O', this is a famous Irish surname. It derives from the pre 10th century Gaelic surname O'Maille, meaning the male descendant of the prince, although who the prince was is not proven. The great O'Maille clan belonged exclusively to County Mayo, and they held sway over the baronies of Burrishoole and Murrisk in that county. Many members were renowned for their prowess at sea which is encapsulated in their motto, "Terra marique potens" meaning "Powerful by land and sea".
