Every family has a story — and JoJo is about to find out just how big hers really is. With Gran Gran's help, she traces her roots all the way back to a great-great-gran gran, discovers that Auntie Dee is actually Mummy's cousin, and learns she was named after an ancestor called Josephine. (JoJo. Josephine. Mind. Blown.) A real-life family then gets their hands literally covered in paint to make their own handprint family tree — because what's better than turning family history into a craft project? This one's guaranteed to send kids running to ask their parents a hundred questions about grandparents and great grandparents!
