Jay Rockefeller is John D. Rockefeller, IV. His father, John D. Rockefeller, III, was born in 1906.Thanks for correcting me. I should have thought more clearly before posting his name.
Isn't it cute, how John D. Rockefeller, IV tries to hide his ancestry behind the name "Jay"?
John D. III died in 1978 in an automobile accident. His siblings Abby, Nelson, and Winthrop died at 73, 70, and 60 respectively. Laurance made it to 94, and David is still alive at the age of 90. Nelson's son Michael probably died at the age of 23 (he disappeared in New Guinea in 1961 and was never seen again).
John D. III's wife was Blanchette Ferry Hooker (1909-1992), so you could say that Jay Rockefeller is the son of a Hooker.
