The surname O'Malley originally appeared in Gaelic as "O Maille."

Research into the name O'Malley revealed many variations, including Malley, Mallay, Mally, O'Mally, Mailley, O'Malley, O'Mailey, Mailey, Maley, Mealey, Mealley, Meally and many more.

First found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they held a family seat from ancient times.

Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name O'Malley:
