During the documentary, Dame Shan spoke candidly about her upbringing and the early responsibilities she was encouraged to take on. She recalled learning from a young age to turn her hand to anything, whether collecting eggs, picking fruit or working on the tractor. Despite her strong attachment to home, she was sent to boarding school in Sussex as a child, an experience she later described as deeply unhappy and isolating.

Alongside managing the estate, Dame Shan took on a wide range of public roles. She served as Lord Lieutenant of Powys and chaired the Brecon and Radnor Country and Land Association. She was also President of Save the Children in Wales, President of the Royal Welsh Agricultural Society and led the National Federation of Young Farmers Clubs.

While her ties to royalty were well known, those who knew her say she will be remembered above all for her devotion to Wales, her community and her family. Her life combined tradition, hard work and quiet influence, leaving a legacy that reaches far beyond her titles.
