I was looking about the death of the Rothschild granddaughter a year or so ago and I found this from 2010.
A member of the Goldsmith dynasty, who was making a documentary about singer Pete Doherty, has been found dead.
Ms Whitehead is the granddaughter of the late Teddy Goldsmith. A post-mortem examination is due to take place.
Teddy Goldsmith was an environmentalist and writer who founded The Ecologist magazine and brother of the late billionaire financier Sir James Goldsmith.

Why Goldsmith, when I look out for Rothschild? Couldn´t find something in english, here translated from German.
Rothschild heiress died after Doherty's visit
Whitehead belonged to the billionaire Rothschild dynasty. Her cousin Jemima Goldsmith was a close friend of Princess Diana, her cousin Zac Goldsmith is one of the young hopefuls of the Conservative Party, and her grandfather was the famous author and philosopher Edward Goldsmith.
