The reason I ask is, I started reading a re-issue of a fantasy novel called Hawkwood's Voyage that I think I read when it first came out, about 15 years ago. As I'm reading along, I come to a map of the continent the story's set on, and I see a name that I've been using for one of my worlds. It's an unusual enough name that there's no way we both could have come up with the same thing independently; the only thing I can think is that it stuck in my head from the first time I read the book, but as the years passed, I forgot where it came from.

Now I feel like I've ripped the author off on some level by using that name. Guess I'll have to do yet another revision and come up with a new name.
