Cudjoe Key, Florida
It is possibly named after the Joewood tree (Jacquinia keyensis), a native species. It is also known as cudjoewood. But writer John Viele of Summerland Key gives a better reason for its name.  He believes that Cudjoe, a very common West African name, was the name of a fugitive slave or free negro who lived on the island at some point before to Gerdes' survey in 1849.
