Attractions will include an Ask the Experts area, where leading genealogists will give free one-to-one guidance on how to research family trees and find elusive ancestors.
The Society of Genealogists will also also be laying on free workshops, while others will have the chance to go online and search the comprehensive files of Ancestrey.co.uk without charge.

The event has been staged each year in London since 2006. This is the first time it's been staged outside the capital.

He said such an event "helps genealogists, from beginners to experts, to further unravel their family history stories."
Scotland's Tourism Minister Fergus Ewing said the event will help businesses and community "tap into the ancestral tourism market."
