You really are determined to ignore what you're being told, aren't you?! D'Oh! | :doh:

It is literally impossible to use a regex to determine whether a sequence of characters refers to a person, a city, a talking kangaroo, or a Vulcan mating ritual.

Your only hope is to get a massive database containing the name of every single city on Earth, and hope that anything that's not in that list refers to a person. And even that's not foolproof - for example, "Paris" could be a city or a person. Without more details, you have no way of knowing.

The data you're trying to process is garbage. If you need to be able to tell whether the data refers to a person or a city, then you need to go back to the people providing the data and get them to add something into the data to distinguish the two. Assuming they know the difference in the first place!
