Only somewhat related but my parents named me a fairly common, if niche in America, name. But they declared it to be pronounced like another common name. For example, naming me Joan but having it pronounced Jane. They claimed that it was some Old World way to pronounce it that they found in a book.

I grew up not thinking about it much (it's my name). I think it even helped me socially a bit when I was younger...it was a pretty good conversation starter. Now that I'm middle-aged, it's an annoying thing I have to state at the start of meetings.

I've since grown tired of correcting everyone and now a lot of people go around calling me Joan, and no one knows who they're talking about anymore :)
