So what happened?

Funny, Lucifer doesn't have the -el.

Very (seriously) interesting comment.
"Ante luciferum, genuite" (Latin - Isaiah ... "before the daystar, I have begotten thee") ... the name came from a reference to the "daystar".
In Latin, the "light-bringer" (ie preceded the sun rise), ie Venus, was the lightbringer, and "fell from heaven" occasionally when it was not visible.
There is also a history of when the word "Lucifer" was mis-translated, which is log and boring. So yes, Lucifer is not one of the Babylonian messengers of the god El Elyon, but the origins of the word and when it was used as a name are pretty well known and understood.

Ah, mythology is fun to play. I called my daughter "sofia", you should know what that means. It would be odd to name her Lucifer, albeit at age 3, she makes me feel otherwise.
