Girl name · 141 babies recorded · 1974–2025

Cassidy: 141 babies born in Scotland since 1974, given to girls, peaking at 11 births in 2009.

Cassidy began as an Irish surname, Ó Caiside, meaning "descendant of Caiside" — a personal name thought to derive from *cas*, "curly-haired." It crossed into Scotland and became a unisex first name, especially popular in the United States before gaining traction here. The most famous bearer is the outlaw Butch Cassidy (real name Robert LeRoy Parker), whose Wild West exploits were immortalised in the 1969 film *Butch Cassidy and the Sundance Kid*. The name also belongs to Cassidy, a small town in British Columbia, Canada, named after a local settler. In music, Cassidy is a stage name for the American rapper Barry Adrian Reese, and the name appears in the classic folk song *The Banks of the Ohio*. A notable variant is Cassie, a common short form.
