Ceusox 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 Ceusox, 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 Ceusox 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 Ceusox family
The surname Ceusox 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. 
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.
