Is there more than one Houston?

Excuse me, but could you clarify something for me? When you mention "Houston," are you referring to a specific location or perhaps there are multiple places with that name? It's quite common for cities and towns to share names, so I'm curious if there's more than one Houston out there in the world. Or are you perhaps referring to a specific district, neighborhood, or region within a larger Houston area? Clarification would be much appreciated.
