Well, I did find this in a quick search fo Yahoo:

We've all heard that phrase before.
But did Sam Hill really exist?

Yes, indeed. He lived in Washington and married the daughter of a railroad magnate. He built a large mansion called Maryhill on 7,000 acres of land. His wife refused to live in the mansion, and it is now a museum that has a stunning collection of Auguste Rodin sculptures. Sam Hill also built a partial replica of Stonehenge as a memorial to veterans of World War I from Klickitat County.
