Chery and Fair-Star.
Chery was the son of a kings brother and Brunetta; Fair-star was the daughter of the king and Blondina, the two fathers being brothers, and the two mothers sisters. They were cast on the sea adrift, but were found and brought up by a corsair and his wife. Ultimately they are told of their birth by a green bird, and marry each other. This tale is imitated from The Sisters who Envied their Younger Sister, in Arabian Nights.
N.B.The name is from the French cher (dear), and is about equal to deary or dear one. It is quite wrong to spell it with a double r. (Comtesse dAulnoy: Fairy Tales.)
