My oldest has a name from one of my grandparents' ancestors (I think their grandparent or great-grandparent) that's not common in my country (my grandparent was an immigrant). The name is easy to pronounce, but unfortunately there's a celebrity with a similar name, so people always mistake it for that name.

The other two are very common here and haven't caused issues. But the one foreign name has been a serious problem, but fortunately my kid loves their name, and it's unique without being a pain to spell.
