When the Anglo-Normans began to settle in Ireland, they brought the tradition of local surnames to an island which already had a Gaelic naming system of hereditary surnames established. Unlike the Irish, the Anglo-Normans had an affinity for local surnames. Local surnames, such as Cosak, were formed from the name of a place or a geographical landmark. Often, these place names were prefixed by "de," which means "from" in French: in later years, the prefix sometimes became joined to the name, or was sometimes dropped. The Cosak family name is thought to have come from any of several places named Cussac in France; such as Cussac in Guienne (Guyenne), Cussac in Limousin, or from Cussac in Auvergne. These place names are thought to derive from Cucius or Cussius, a Romano-Gallic personal name, along with the suffix "-acum." After the name came to Ireland, it took on the Gaelic form Ciomhsóg. However, in the county of Clare, the Gaelic form of the name is Mac Iosóg.

Early Origins of the Cosak family

The surname Cosak was first found in County Meath (Irish: An Mhí) anciently part of the kingdom of Brega, located in Eastern Ireland, in the province of Leinster, where Jeoffrey Le Cusack was first recorded. He was named after a town of that name in France and came to Ireland shortly after the English invasion. Adam Cusack, his grandson "slew William Barret and his brothers in Connaught, on account of a quarrel about lands " in 1282. 1

Walter de Cusack (c.1270- 1334) was an Anglo-Irish judge, magnate and military commander of the fourteenth century. He was a younger son of Sir Andrew Cusack of Gerrardstown, County Meath. Nicholas Cusack, Bishop of Kildare (1279-1299), was a cousin.

Another reference has a slightly different twist on the origin in France. In this reference, the name "is derived from a place in Guienne, France, and was first anglicized as de Cussac." 2 Whichever origin is true, the occurrence of the name in England was indeed rare.

Migration of the Cosak family

The Irish emigration during the late 18th and 19th century contributed to the melting pot of nationalities in North America, and the building of a whole new era of industry and commerce in what was seen as a rich, new land. Ireland'sGreat Potato Famine resulted in the worst economic and social conditions in the island's history. And in response to the hunger, disease, and poverty, during this decade the total number of emigrants to leave for North America rivaled all the previous years combined. Those from this decade that arrived on North American shores were not warmly welcomed by the established population, but they were vital to the rapid development of the industry, agriculture, and infrastructure of the infant nations of the United States and what would become Canada. Research into early immigration and passenger lists has shown many people bearing the name Cosak: Christopher Cusack who settled in Philadelphia, Pennsylvania in 1830; Betsey Cusack settled in Boston Massachusetts in 1849; Pat Cusack settled in Canada in 1839.
