Billed as the UK's first ever national history show, "Who do You Think You Are? LIVE" will provide "expertise, interaction and entertainment" to teachers and pupils who wish to study their ancestors' history.
Taking place at Kensington Olympia in London from May 5-7, the event will consist of talks, workshops and expert panels, including David Starkey, the historian, and Nick Barratt, the genealogist.
Celebrities such as Colin Jackson and Ian Hislop, whose family histories featured on the BBC television programme that inspired the exhibition, will also appear. Visitors will be able to look at family, property, military and social history.
