Donny Osmond will play a concert next June in Merthyr Tydfil, South Wales, the hometown of some of his ancestors.
Utah-born Osmond travelled to the town last year to track down his heritage and succeeded in tracing his family roots back 500 years.
He found the grave of his great, great, great grandfather Dr John Martin who was chief surgeon at the local steelworks.
He also found that his family fled to America to escape the dangers of mid-19th century cholera outbreaks and not to flee religious persecution as was first thought. [Link]
