Possibly derived from Cayman meaning crocodile or a literary invention.
The name Khayman is most notably recognized as a literary creation by Anne Rice for her 'The Vampire Chronicles' series. While it lacks a traditional etymological history, it is phonetically similar to the Spanish word 'caimΓ‘n' for crocodile or the Arabic name Ayman. In a modern context, it is chosen for its unique, exotic sound and its association with gothic literature.
