When I first came across the name
Jezebel I wasn't familiar with the Biblical
Jezebel and I thought some people were overreacting when they said that it was totally unusuable. But I spent a few months in
Ireland last year and I heard the expression "dirty jezebel" etc enough to agree with those who thinks it's unusable. I think it works for a character though.
There was an article in the newpaper not long ago where a ten year old girl was named
Jezebel. It honestly made me wonder if the parents realised what they had named their daughter. I live in a very secular country and I think the majority would not have a clue who the Biblical
Jezebel was. I still think it's a bad idea.
