Meaning and background
The story behind Cassidy
Cassidy began as an Irish surname before becoming a given name in English. The family name Ó Caiside identifies descent from an ancestor named Caiside; accounts also connect that older personal name with curly hair. That is surname history, not a description of a dog called Cassidy. The three-syllable form gives the owner an obvious short alternative, Cass.
