YouTuber and actor Joe Sugg uncovers some incredible stories in his family tree, with a little help along the way from fellow social media star and big sister, Zoe. 

Joe, very aptly, discovers a great-great-great-grandfather who was involved in the earliest days of communications technology – in electrical telegraphs. 

Pushing further back, he finds seven-times-great-grandparents who fled religious persecution in France, and a goldsmith who survived the Great Fire of London.
