The Story of Kassidy

Kassidy is a variant spelling of Cassidy, which derives from the Irish Gaelic surname Ó Caiside, meaning 'descendant of Caiside.' The personal name Caiside is thought to mean 'curly-haired' from the root 'cas' (curly). Like many Irish surnames, Cassidy transitioned into first-name use in America during the 20th century as part of the trend of using Celtic surnames as given names, a pattern especially popular for girls.

Cassidy surged as a girl's name in the 1990s and 2000s in the United States, partly inspired by the legendary American outlaw Butch Cassidy and the beloved 1969 film. The K-spelling Kassidy emerged as a creative variant for parents wanting distinction. Various TV characters named Cassidy also boosted its popularity throughout this period.

Cassidy is deeply connected to American Western mythology through the outlaw Butch Cassidy (born Robert LeRoy Parker). As a girl's name, it represents the American tradition of reclaiming surname names — particularly Western-sounding ones — as first names, investing them with adventurous, free-spirited energy.
