America's 15 richest women contain two groups of sisters, philanthropic heiresses, widows of entrepreneurs and tech moguls and one self-made billionaire. The 15 women on this list are collectively worth $217.5 billion. Multiple members of the Mars family and Walton family make the list including two sets of sisters. Mackenzie Bezos makes the list for the first time, thanks to her divorce settlement from Jeff Bezos.
