Why would someone name one street Connor, and the next one O'Connor?
There are two towns not too far from my house named "Guin" and "Gu-win". I think it's the most idiotic thing I've ever seen.

"Gu-Win" and "Guin" are not the same, though the pronunciation is virtually the same, leading to occasional confusion by visitors.
