What Does the Name Kassidy Mean?

Kassidy is a variant spelling of Cassidy, an Irish name traditionally meaning "curly-haired." It comes from the Gaelic surname Ó Caiside, a patronymic meaning "descendant of Caiside." Caiside was a personal name or byname, usually connected with the Irish word cas, "curly" or "twisted." The K spelling is an English-language variant of the same name, not a separate Irish form.

Kassidy Name History & Origins

The name comes from the Irish surname Ó Caiside, which arose in Gaelic Ulster. As a patronymic, it identified a person as a descendant of Caiside. The family associated with the surname was centered in County Fermanagh, and traditional accounts describe the Ó Caiside as a learned family, hereditary poets to the Maguire lords of Fermanagh. The surname was anglicized in various forms, including Cassidy and O'Cassidy, and it spread to English-speaking countries through migration.

Cassidy later became a given name in the English-speaking world. Kassidy is a modern spelling variant of that given name. The initial K is an English respelling; the Irish language traditionally uses C, so the change does not reflect a different Gaelic origin. The name's development as a first name is therefore tied to the history of Cassidy rather than to an independent Irish personal name.
