The name Casin is of Gaelic origin, derived from the diminutive form "Caisín," which means "curly or twirled" in Irish. Historically, the name has been associated with the Normans who brought it to England after the 1066 conquest. Over time, the spelling has varied, including Cassan, Cassane, and Casson. The name's significance lies in its unique cultural heritage and the historical context of its introduction to England and Ireland.
