About the name Rex

Rex is derived from the Latin word rex, meaning king, and is related to regere, ‘to rule’, and to the English words regal and reign. It was used for the early kings of Rome and later appeared in the formal Latin titles of English monarchs, as in Georgius Rex. As an English given name it came into use in the nineteenth century, partly as a short form of Reginald. Rex Harrison was a famous British actor who won an Academy Award for playing Professor Henry Higgins in My Fair Lady.
