O'Coalghan History, Family Crest & Coats of Arms
- Origins Available:
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'Coalghan surname stems from two distinct Gaelic names O'Clúmháin, derived from the Irish root "clúmh," meaning "down," or "feathers," and from O Colmain, derived the Latin word "columba," which means "dove." 
Early Origins of the O'Coalghan family
The surname O'Coalghan 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.

The common practice of recording names as they sounded resulted in spelling variations such as Colman, Coleman, O'Colman, MacColeman, McColeman, Coalman, Coulman, Colemen, Colmen, Coalmen, Colmin, Colmen, Coulmen, Coulmin, Colemin and many more.

Migration of the O'Coalghan family
The 19th century saw a great wave of Irish migrating out of their homeland in a great measure due to the oppressive imperial policies of the English government and landowners. Many of these Irish families sailed to North America aboard overcrowded passenger ships. By far, the largest influx of Irish immigrants to North America occurred with Great Potato Famine during the late 1840s. These particular immigrants were instrumental in creation of the United States and Canada as major industrial nations because the many essential elements such as the roadways, canals, bridges, and railways required an enormous quantity of cheap labor, which these poor immigrants provided. Later generations of Irish in these countries also went on to make valuable contributions in such fields as the arts, commerce, politics, and education. Extensive research into immigration and passenger lists has revealed many early immigrants bearing the name O'Coalghan: 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.
