Some names (eg Raj, Sven, Chad, Ling) have pretty strong hints as to which country or region that person may be from.
Which names, to you, are very difficult to place? So if you heard the name, you wouldn't assume them to be from any particular continent or country.
So what works in many regions and languages, in terms of not being totally "out there", and not being too hard to pronounce in any language/ accent?
I'm struggling to think of ANY right now!
