There are many Irish surnames being used today in forms that are quite different than their original, ancient forms. McMannus originally appeared in Gaelic as Mac Maghnuis, which means son of Manus. The personal name Manus, imported into Ireland by the Norse, is ultimately derived from the Latin forename Magnus.


The surname McMannus was first found in County Roscommon (Irish: Ros Comáin) located in central Ireland in the province of Connacht, where they held a family seat from ancient times.

People who were accounted for by scribes and church officials often had their name recorded many different ways because pronunciation was the only guide those scribes and church officials had to go by. This resulted in the problem of one person's name being recorded under several different variations, creating the illusion of more than one person. Among the many spelling variations of the surname McMannus that are preserved in archival documents are MacManus, MacManners, McManus, Manus and others.

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North Ameri ca. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world.
