Following her family tree, the show initially takes Keegan to Gibraltar where her great-grandmother was born. Then, after learning of her great-grandmother’s evacuation to London in the Second World War, she travels back to the UK and Manchester, where she unearths her connection to the suffragettes.   


A BBC1 clip shows Keegan faced with her great grandmother’s birth certificate. She appears relieved to avoid yet another certificate of a family death as she reads the signature of Emmeline Pankhurst. As well as being one of the leaders of the suffragette movement, Pankhurst was also the registrar of the Chiltern upon Medlock district, where Keegan’s grandmother lived.
