Coousseck History, Family Crest & Coats of Arms
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 Coousseck, 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 Coousseck 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 Coousseck family
The surname Coousseck 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. 
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."  Whichever origin is true, the occurrence of the name in England was indeed rare.

Migration of the Coousseck family
Irish immigration to North American began in the late 18th century as many Irish families desired to own their own land. This pattern of immigration grew slowly yet steadily until the 1840s. At that time, a failed crop and a growing population in Ireland resulted in the Great Potato Famine. Poverty, disease, and starvation ravaged the land. To ease their pain and suffering the Irish often looked upon North America as a solution: hundreds of thousands undertook the voyage. Their arrival meant the growth of industry and commerce for British North America and the United States. For the individual Irishman, it meant survival and hope, and the opportunity for work, freedom, and ownership of land. The early immigration and passenger lists revealed many bearing the name Coousseck: Christopher Cusack who settled in Philadelphia, Pennsylvania in 1830; Betsey Cusack settled in Boston Massachusetts in 1849; Pat Cusack settled in Canada in 1839.
