Kasey

Kasey is a diminutive form of the name Casey, which is derived from an Irish surname. The surname Casey is believed to be an anglicized version of the Irish Gaelic name 'O'Cathasaigh', which means 'descendant of Cathasach'.

The name Cathasach is derived from the Irish Gaelic word 'cath', meaning 'battle', and 'saor', meaning 'free' or 'noble'. Therefore, the name Cathasach translates to 'battle-free' or 'noble in battle'.

The name Casey and its variant spellings, such as Kasey, became popular in the United States in the late 19th and early 20th centuries. While it was initially used as a surname for people of Irish descent, it eventually gained popularity as a given name as well.

Today, Kasey is a unisex name, although it is more commonly used for boys. It is a name that carries a sense of strength, courage, and nobility due to its Irish heritage and meaning.
