I experience the opposite. I have the Irish name 'Cathal' which isn't very well known outside of Ireland. I've spent the past year in the US and every time I'm introducing myself to someone I hesitate and mentally prepare for the 'wait what?' after I tell them my name.

It's common here for restaurants and cafes to ask for your name when ordering, and often I'll make up a more common name for myself to avoid the hassle spelling out and explaining 'Cathal' to the cashier.

Having a unique name does however create an interesting talking point when talking to a new person, and it seamlessly opens up a discussion about my background and origins after introducing myself.
