HOW far back does your family tree go?
All the way back to Mary, Queen of Scots?
Genealogy enthusiasts will flock to the SECC tomorrow and Saturday for the first-ever Who Do You Think You Are? Live Scotland event.
Supported by Homecoming Scotland, it will help family historians to unravel their roots and build a picture of their ancestors' lives.
It will be home to experts, workshops, archives and museums, online subscription sites and one of the largest gatherings of family history organisations.
Show director Andy Healy said: "It's a must-attend event for anyone with an interest in family history."
And if you don't turn out to be related to Mary ... well, there's no need to lose the head about it!
