I knew a girl who went by that name but I've always assumed it was just her nick name. One Monday two of the mechanics my dad worked with came in to work talking about these two girls they picked up over the weekend named "Angel and Susan" (or some variation of that name). Meanwhile, "Cheryl and Renee" came to school Monday morning talking about these two older guys they hooked up with over the weekend. Didn't take a lot of connecting the dots to figure out the rest of the story. Angel and Renee were the same person and about 17 Y/O at the time, the other girl was a bit younger.

There was a very popular user here about 4 years ago that went by that name.

I knew a few by the name of Angela but they would answer to Angel too

Thats my name

Angel is short for Angela

Not so many anymore. It seems to go back and forth. For the record, in the original Hebrew, it's a masculine name.
