Barnsley farmers Rob and Dave Nicholson head to Halifax to find out more about their mum's side of the family. They start at Dean Clough Mill where their mum Cynthia started work as a 15 year old before heading to the Shibden estate – a place grandma Olive took them for days out as kids. It's their first trip back in 40 years. They also look inside the home of celebrated diarist Anne Lister, aka Gentleman Jack, and visit the kitchen their great grandmother Eliza worked in as a cook in the 1900s.
