src: Wikipedia The combined wealth of the family - its total assets and investments plus the individual wealth of its members - has never been known with any precision. In 1992, family members estimated it to be between US$5 billion to $10 billion. The records of the family archives relating to both the family and individual members' net worth is closed to researchers. From the outset, and even today, the family wealth has been under the complete control of the male members of the dynasty, through the family office. Despite strong-willed wives who had influence over their husbands' decisions - such as the pivotal female figure Abby Aldrich Rockefeller, wife of Junior - in all cases they received allowances only and were never given even partial responsibility for the family fortune. Much of the wealth has been locked up in the notable family trust of 1934 (which holds the bulk of the fortune and matures on the death of the fourth generation), and the trust of 1952, both administered by the Chase Manhattan Bank.
