Diana 

Said to have been a goddess who had a daughter named Aradia from a union with Lucifer.

Now used as a rather common first name for females. (Most of the the girls I have met with this first name were quite attractive, for whatever that is worth.)

Diane seems to be a variation of Diana.

A very attractive young lady named Diana Spencer (Princess Diana) was married to Prince Charles.  She was killed in a car crash in a tunnel in France, in a car driven by her last lover. (As far as I know the Freemasons have not yet been blamed for causing her death, but someone will probably blame us for it at some time in the future.  If asked, President Obama will probably blame her death on George Bush, as he blames everything else!)
