The meaning and origin of the last name Cahill
The surname Cahill is an Anglicized form of the Irish name Ó Cathail, which means "descendant of Cathal." The name Cathal originates from the Gaelic word 'cathal' meaning 'battle,' indicating that it was a name given to someone associated with battles or war. Over time, as Irish people migrated and assimilated into other cultures, particularly in England and Scotland, their names were often Anglicized. In this case, the Irish Ó Cathail became Cahill, Cahell, or Kelly in English-speaking countries. The name is relatively common among Irish descendants worldwide, particularly in North America.
Geographical distribution of the last name Cahill
The surname Cahill is predominantly found in Ireland, with the highest concentrations in counties such as Cork, Kerry, Limerick, and Galway. Historically, these regions were part of the Gaelic kingdom of Munster, where the name originated from the Irish clan Ó Cathail or MacCarthy Mor. Over time, emigration due to famine and economic reasons led to a significant dispersion of Cahills across the world. In North America, large numbers are found in the United States, particularly in states with high Irish-American populations like Massachusetts, New York, and Pennsylvania. In Canada, Ontario, Quebec, and Nova Scotia have notable Cahill communities. In Australia, Cahills can be found in the urban centers of Sydney, Melbourne, and Brisbane. The surname has also spread to other English-speaking countries like England, Scotland, and New Zealand, as well as South Africa due to historical migration patterns.
