It is not actually an island but includes a narrow peninsula which may at one time have been cut off by the sea. The name of the townland is recorded as Conningsiland in 1635, as Cony Is in 1640 and as Conny-Island in 1669. Coney or Cony is a medieval English word meaning rabbit.[3]
"Coney Island" is a spoken-word song written by Northern Irish singer-songwriter Van Morrison and included on his 1989 album, Avalon Sunset. In the song he revisits his youthful trips with his mother to the seaside at Coney Island.[5]
