About the name
Cassidy is Irish — Ó Caiside, "descendant of the curly-haired one" (with "clever" riding along in folk use) — a surname that Hopalong Cassidy westerns and a Grateful Dead ballad turned into a given name.
Cassidy peaked in the American top 100 in the late 1990s and holds steady use — a Y2K-era signature aging into its own vintage.
The name is a lasso thrown with a smile. Cass and Cassie both wear well. It pairs with classic middles (Cassidy Jane, Cassidy Rose). On our vibe map it is Y2K Nostalgic with Boho trail dust.
