The name McLeary originally appeared in Gaelic as Ó Cleirigh, from the word "cleireach," which means "clerk" or "cleric." 1 The name denotes a descendant of Cleireach, who was born around 820 AD, and descended from Guaire the Hospitable, the famous king of Connacht.

Early Origins of the McLeary family

The surname McLeary was first found in County Galway. A descendent of Guaire, Cleireach, the namesake of the O'Clerys, was born around 820 AD, about two hundred years before hereditary surnames came into general use. 2 However, the name O'Clery first appeared around 950 AD, making it one of the earliest recorded hereditary surnames. The O'Clerys were the dominant sept in what is now the diocese of Kilmacduagh in the county of Galway, but declined in power until they were forced out of their original territory by the mid-13th century. The most important branch of the family settled in Counties Derry and Donegal and became prominent historians and poets. The branch that settled in County Cavan has seemingly all but vanished. However, the English surname Clarke has been widely substituted for O'Clery there, following the Plantation of Ulster, and many Irish Clarkes may actually be O'Clerys, rather than descendants of English settlers. Another branch is still fairly common in the counties of Kilkenny, Waterford, and Tipperary. The name is presently found mostly in Munster and Dublin.

Canada McLeary migration to Canada +

Under the rule of England, land ownership in Ireland changed dramatically, and many native Irish families found themselves renting out land to farm from absentee owners. This was one of the prime reasons that immigration to North America began in the late 18th century: Irish farmers dreamed of owning their own parcel of land to work for themselves. At this point, the immigrants were at least of modest means for the passage across the Atlantic was often quite dear. In the 1840s the Great Potato Famine created an exodus of people of quite different means. These people were most often destitute: they either sold anything they had to gain a passage or they were sponsored by philanthropic societies. Many of these immigrants were sick from disease and starvation: as a result many did not survive the long transatlantic journey. Although those settlers that did survive were often despised and discriminated against by people already established in these nations, they were critical to rapid development of the powerful industrial nations of the United States and the country that would later become known as Canada. An examination of immigration and passenger lists shows many persons bearing the name of McLeary or one of its variants:
