Casey: What does the surname Casey mean?

The last name Casey is of Irish origin, derived from the Gaelic name "O'Cathasaigh". It consists of two elements – 'cathasach' meaning 'watchful' or 'vigilant', and 'O' prefix meaning 'grandson' or 'descendant of'. Therefore, it roughly translates to 'descendant of the vigilant one.' The Casey family originated from various parts of Ireland, including Roscommon, Cork, and Dublin. Over time, the family name spread across the world due to Irish diaspora during the Great Famine in the 19th century. Today, it is a common surname found in many English-speaking countries. The family motto, "Per Varios Casus", translates to "By Various Fortunes", which perhaps reflects the resilient spirit of the Casey clan throughout history. There are various prominent personalities with the surname Casey, across fields like politics, literature, sports, and entertainment.

Casey: Where does the name Casey come from?

The surname Casey has Irish roots and derives from the Gaelic Ó Cathasaigh or Ó Casaide, which means descendant or son of Cathasaigh. The personal name Cathasaigh is a combination of two Gaelic elements: "cath", which means battle, and "saigh", which means lazy. Thus, this surname may denote the progeny of a warrior or a vigilante.

Different septs (branches of a clan) of the Casey family were located in various regions of Ireland, including Dublin, Kerry, Fermanagh, and Roscommon. Despite the dispersion over several counties, the Casey family has a strong presence in Munongh, Cork, and Clare. Emblematically, the family crest bears the motto "without fear".

Today, the surname Casey is prevalent in Ireland, the United States, England, Canada, and Australia. The largest concentration of people with this surname, however, is found in the United States. This can be easily attributed to the Irish diaspora's prominent movement to North America during the Great Famine in the mid-1800s. Consequently, despite its Irish origin, the name Casey is now a popular surname worldwide.

Variations of the surname Casey

The surname Casey is Irish in origin, derived from the Gaelic "O'Cathasaigh." Over time, there have been many variations in spelling due to a combination of regional dialects and translations. These include: O'Casey, O'Cassidy, Caice, Cash, Cassey, O'Caise, Kacy, O'Kasey, McCasie, Keasey, and O'Kacey.

Some variations are common surnames themselves, like Cassidy, while others may be fairly rare. There are also cases where Casey could have been changed or altered through the course of immigration or anglicisation, leading to a variety of other possible surnames.

Please note that while these names may have similar spellings or sound similar, that doesn’t always mean they share the same origin or meaning. For example, the surname Cash, while similar in spelling to Casey, is generally of English origin, not Irish.
