Blair Parry-Okeden, 60
$6.7 billion
Cox Enterprises, U.S.
Granddaughter of Cox Enterprises founder James M. Cox (d. 1957), Parry-Okeden inherited 25% stake in business after mother, Barbara Cox Anthony, passed away in 2007. Not active in family business, Parry-Okeden lives in near anonymity in Australia, making her one of that country’s richest residents. Brother Jim, who also got a 25% stake, is chairman of the nearly $15 billion (revenues) group.
