Ah, my fairly unusual maiden name is on the world names profiler. One of the "most frequent" places is Texas, United States, and zooming in on the map, the sole concentration is in the county where I grew up. What a coincidence (except definitely not, haha!) The other more frequent places are the UK & Canada (makes sense, I'm from the Caribbean and those countries have loads of Caribbean people.) and France (which also makes sense, because it's a French name.) The profiler says my maiden name is Jewish though, which is weird.
