While the Anglicized versions of Irish names are familiar to most people, many Irish names have a long and proud Gaelic heritage that is often unknown. The Cooalehan surname stems from two distinct Gaelic names O'Clúmháin, derived from the Irish root "clúmh," meaning "down," or "feathers," and from Ó Colmain, derived the Latin word "columba," which means "dove." 1

Early Origins of the Cooalehan family

The surname Cooalehan was first found in County Sligo (Irish: Sligeach), in the province of Connacht in Northwestern Ireland, where they were a sept of O'Colmain, a branch of Hy Fiachrach. 2

Migration of the Cooalehan family

Ireland saw an enormous decrease in its population in the 19th century due to immigration and death. This pattern of immigration began slowly in the late 18th century and gradually grew throughout the early portion of the 19th century. However, a dramatic increase in the country's immigration numbers occurred when the Great Potato Famine struck in the 1840s. The early immigrants to North America were primarily destined to be farmers tending to their own plot of land, those that came later initially settled within pre-established urban centers. These urban immigrants provided the cheap labor that the fast developing United States and soon to be Canada required. Regardless of their new lifestyle in North America, the Irish immigrants to the United States and Canada made invaluable contributions to their newly adopted societies. An investigation of immigrant and passenger lists revealed many Cooalehans: Thomas Coleman, who arrived in America from Marlborough in Wiltshire, England; Thomas Coleman settled in Newbury, and later Boston, Massachusetts. He was under contract, but not indentured to Sir Richard Saltonstall, to keep his cattle. He was negligent and unfaithful, as the court ruled, but, strangely a year later in 1637.
