One link in the chain of off-shore islands extending from Anclote Key southward along Florida’s Gulf coast is Casey Key in Sarasota County. This little Key has more than its share of natural beauty and charm yet remains one of the least known islands. Although little is heard of Casey Key, except locally, for which the residents who value privacy are grateful, even more obscure is the origin of the name. One historian has written, “When and how Casey’s Pass was named no one knows. According to waterfront legend an Irishman named Casey settled there for a number of years early in the 19th century and left during the War of 1812. Rut that is only legend.” It seems fitting and proper that a closer acquaintance be had with Captain John Charles Casey and that he receive credit for the role he played in the early history of Florida. Recent attempts to glamorize this island paradise by changing its name to the insipid title of Treasure Island have, happily, failed and the euphonious and distinctive name it has had for more than a century remains.
