Oliver Rothschild, who claimed to be part of the ninth generation of the prominent Rothschild family, has been active in a variety of high-level business in China over the past few years. But his identity claims were recently debunked by real family members in the U.K.

The Rothschild family, one of the wealthiest families in the world, is seldom out of the limelight for long. The family was recently in the news in China after the publication of “Currency Wars,” a bestseller claiming that the Rothschild financial empire deeply affected the development of Europe. The book sparked wide-ranging debate, and the family continues to intrigue the public.

With a charming British accent, paired with a special last name, Oliver Rothschild was regarded as heir of the mysterious Jewish banking family for several years.

He has been active in China’s business arena recently, showing up to many high-level events organized by colleges, institutions and think tanks. At the end of January, he attended a roadshow in Beijing. Three days later, he was invited by Tsinghua University to give a speech.

According to the press release from Tsinghua University, Rothschild visited China a number of times in 2013 and 2014, during which time he met with many high-profile Chinese entrepreneurs and government officials.

In both 2015 and 2016, his busy agenda in China has included inspections of Chinese cities, talks with business heavyweights, visits to firms, attendance of international events like the China-Arab States Expo, and delivering speeches in various forums.

The press release also stated that Rothschild was introduced as a core member of the U.K. line of Rothschilds. He was additionally named as head of dozens of welfare and charity organizations, including UNICEF and the British Red Cross.

UNICEF confirmed to the Economic Observer that Oliver Rothschild was a supporter of the organization in 1990s; however, due to insufficient records, they could not verify his specific contributions.

“But we are certain that UNICEF currently has no connection with him in any form,” the charity spokesperson added.

The British Red Cross also denied employing Rothschild, and was unable to elaborate on his prior contact with the organization.

“We have confirmed that Oliver Rothschild is not a member of the Rothschild family. That is, he is not a male descendent of Nathan Mayer Rothschild, and he is not involved in any of our business,” read a reply from a representative of the U.K. branch of N.M. Rothschild & Sons Limited, also referred to as the Rothschild Group.

Meanwhile, Oliver Rothschild was found not to be registered on www.rothschildarchive.org, a detailed online archive of the family. Neither does the website have any information regarding the family’s ninth generation.

Rothschild was, however, proven to be the head of Oliver Rothschild Corporate Advisors Limited, a consulting firm in the U.K. The company’s LinkedIn page said it had been founded in 2007, and its headquarters are in London. Based on public account information, the company’s total liability had reached 80,780 pounds by the end of 2014, while its total assets were worth just 9,633 pounds.

Beyond the consulting firm, Rothschild has been on the boards of nine companies since 2009. Astelios Limited, the only one that is still operating, has a negative net worth of 19,912 pounds.

Rothschild Group declined to comment on the story.
