The Du Pont family is one of the wealthiest families in America, and they’ve been successful since the 1800s when they founded the Du Pont Company. The Du Ponts have their fortune in the gunpowder business, and they’ve amassed not only billions of dollars, but also quite a property portfolio.

One holding of the Du Ponts is Cherry Island, located off the coast of Maryland. The Du Ponts have owned Cherry Island since 1831, and there are pictures of the family vacationing there for generations. Cherry Island has been passed down through the family over time, keeping it privately-owned.
