Cassidie is an uncommon, distinctive feminine given name of Latin origin. It is derived from the Roman family name Cassius, which means 'hollow' or 'curved'. The name gained popularity in recent years due to its unique sound and spelling, appealing to parents seeking a less common yet elegant choice for their daughters.
"Cassidie's popularity peaked in the late '90s and early 2000s, with a high of 31 births in 1998. However, it has since declined, reaching a low of 5 births in recent years (2014). Overall, there have been 464 Cassidies born between 1981 and 2017."
