Permira Advisers has agreed to acquire Ancestry.com for about $1.6 billion, Bloomberg reports. The London-based private equity firm will pay $32 a share for the family-history Web site, the companies said today in a statement. “The price is 41 percent higher than Ancestry.com’s closing price on June 5, the last day of trading before press reports that the company had hired a financial advisor for a possible sale,” Bloomberg writes.
