Hector has occasionally been used as a given name since the Middle Ages, probably because of the noble character of the classical hero. It has been historically common in Scotland, where it was used as an Anglicized form of Eachann.
According to the Old Testament Jezebel was the Phoenician wife of Ahab, a king of Israel. She is portrayed as an evil figure because she encouraged the worship of the god Ba'al. After she was thrown from a window to her death her body was eaten by dogs, fulfilling Elijah's prophecy.
As a given name it was mostly masculine before 1940, but it rose in popularity as a name for girls during the 40s and 50s, probably due both to Grace Kelly (who married Prince Rainier III of Monaco in 1956) and a female character on the 1957 television series Bachelor Father [1]. By the end of the 1970s it was on the decline.
