In Kent, the house clearance of a retired lathe operator uncovers a large family, but surname changes don't add up and illegitimate births mean many won't be entitled. Delving deeper into the family tree, missing family records reveal two sister war brides who married their GI sweethearts, but had a fight on their hands to be reunited with them on the other side of the Atlantic. Another team working a Midlands case uncovers a grandmother who made cigars for a living in the thriving tobacco industry. Struggling to locate any heirs on one side of the family, a possible writing error on a census leads them up the wrong track before an eventual breakthrough reveals a large family. But just as the case is turning into a winner, a chance find might see it slip through the Heir Hunters' fingers.
