What's the deal with Hyde Park?

It's weird. It seems that every major city has a Hyde Park neighborhood near it or in it.

Chicago has a Hyde Park on the South Side.

Los Angeles has a Hyde Park.

London, of course, has a Hyde Park.

There's a Hyde Park outside of New York City, I believe on Long Island.

Cleveland, Ohio has a Hyde Park.

For God's sake, there's even a Hyde Park in Cincinnati.

Just an observation. I guess there's a law that if you found a big city, you have to name one of the neighborhoods Hyde Park, or at least make a pact with a neighboring city that that city be named Hyde Park.
