McClary History, Family Crest & Coats of Arms
- Origins Available:
The name McClary originally appeared in Gaelic as O Cleirigh, from the word "cleireach," which means "clerk" or "cleric." 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 McClary family
The surname McClary 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.  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.

| McClary migration to the United States ||+|
A great wave of Irish migration occurred during the 19th century as a direct result of English colonial rule and tight-fisted absentee landlords. Many of these Irish immigrants boarded passenger ships bound for North America. Those who migrated early enough were given land in either British North America or the United States; those who came in the late 19th century were typically employed in industrial centers as laborers. At whatever age they undertook the dangerous passage to North America, those Irish immigrants were essential to the speedy development of the two infant nations to which they arrived, whether they broke and settled land, helped build canals, bridges, and railroads, or produced products for consumer consumption. An examination of immigration and passenger lists has uncovered a large number of immigrants bearing the name McClary or one of its variants:
