The interesting thing about
Janet Libra is that she was listed as one of the deceased's mother (I can't remember which obit. it was in), so she would have been born probably sometime in either the late 1800s or the early 1900s, and I wouldn't think that they would use Libra all the way back then, but there it is.
I do agree, though, Dolor is terrible. If you are going to give your child a word for a name, why would you pick one that has such an unpleasant meaning. It's like naming your child depression or something.
