Tamara Gustavason, Kentucky
Gustavson's $5.3 billion fortune comes from the self-storage business. She is the largest shareholder of Public Storage, which her father co-founded in 1972. She held the vice president position until 2003 when she left to have a family. She now lives at the Spendthrift Farm, where she raises and breeds thoroughbred racehorses.
Gayle Benson, Louisiana
Benson's $2.9 billion fortune is thanks to her sports enthusiast husband. He formerly owned the New Orleans Saints and New Orleans Pelicans until his death. She succeeded him as the owner of both teams. Unfortunately, she entered into a legal battle with his daughter and grandchildren, which was eventually settled privately.
