TIM FAULKNER — Fortune reports that Anne Wojcicki's 23 And Me, a genetic genealogy startup, is getting press attention for something other than her billionaire husband, Sergey Brin, and connections to his company, Google. The firm has determined that Warren Buffett, billionaire investor and philanthropist, and Jimmy Buffett, beach bum singer and restaurateur, are not related as they had long suspected... at least not in the last 10,000 years.
