Here are some infrequently used Judeo-Christian names:
Jezebel
The name of Jezebel, the Queen of Israel, later became shorthand for a fallen woman. "This is a case of a name attracting a degree of notoriety," says social psychologist Dr Martin Skinner of Warwick University. "No-one is going to give their child a name that has taken on negative associations - in this case, with a certain type of woman. To most people, this is better known than the fact that Jezebel was, in the Old Testament, like Eve, Ruth or Naomi."
Dorcas
Dorcas was a faithful female disciple "full of good deeds" whose death prompted much weeping, according to the Book of Acts in the New Testament. She is also known as Tabitha, a name that is much more commonly heard.
Gomer
Gomer was the wife of the prophet Hosea. "To Anglo Saxon ears, there's a sort of masculinity about the sound of Gomer," says Mr Skinner. "Feminine names tend to be lighter - Nicola, Pamela and so on. Men's names tend to be sharper, like John, Jack or Sid."
Achsah
Achsah was the daughter of Caleb, who offered her in marriage to Othniel in the Old Testament.
Wilgefortis
According to a story dating back to the 14th Century, Saint Wilgefortis took a vow of virginity when she was promised in marriage by her father. Following her prayers for help, she grew a beard and moustache.
Zipporah
Zipporah, wife of Moses and daughter of Jethro, was mentioned in the Book of Exodus.
