America may not be home to any rich royal families, but that doesn't mean some families haven't created their own sort of empire.

In fact, the United States has quite a few billionaire clans who accumulated their fortunes in vastly different ways. There are the publishing powerhouses that built the Hearst and Newhouse family fortunes; a cosmetics giant, which laid the foundation for the Lauder family fortune; and the families that created their wealth out of household names, like Walmart for the Waltons and Hyatt Hotels for the Pritzers.

But not all of America's richest families began as entrepreneurs — some were also savvy investors.
