Lorelai apparently doesn't have too much of a meaning. There is a rock in Germany called Lorelei. The rock has a lot of folk lore behind it. The name Lorelai/Lorelei is in a lot of movies/shows/books/music because of that folk lore though!
That being said.. please don't share personal information in this thread. I know real names and locations are easy to let slip out when you are trying to communicate. If your user name has part of your real name, don't say it is! I'm not saying any of you have shared anything too personal so far. I am saying, be careful! We will have to post a bunch of puppies and cats in here if you guys start sharing too much personal information.
This is a fun thread though! I love name meanings.
