Cassady is a variant spelling of Cassidy, an anglicized form of the Irish surname O'Cassidy, from the Gaelic "Caiside," believed to derive from "cas" meaning "curly-haired" or possibly "ingenious." The -ady spelling gives the name a slightly softer look than the more common Cassidy while preserving the same bright, energetic sound. Irish surnames made the transition to first names in English-speaking countries over the 19th and 20th centuries as heritage naming became popular.
