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 O'Colehan 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

Migration of the O'Colehan family

Irish families began to immigrate to British North America and the United States in the 18th century, but the greatest influx of Irish immigrants came during the Great Potato Famine of the late 1840s. The earlier settlers came to North America after a great deal of consideration and by paying relatively high fees for their passage. These settlers were primarily drawn by the promise of land. Those later settlers that came during the 1840's were trying to escape the conditions of poverty, starvation, disease, and death that had stricken Ireland. Due to the enormity of their numbers and the late date of their arrival, these immigrants primarily became hired laborers instead of homesteading settlers like their predecessors. An exhaustive search of immigration and passenger lists has revealed many Irish immigrants North America bearing the name O'Colehan: 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.
