The channel is run by Julie Montagu, now Countess of Sandwich as her husband inherited the Earldom a few months ago when his father sadly died, and her team. If you are interested there are other channels which she and her husband run and present. They are all excellent
American Countess - by Julie
Mapperton Live: This (un)Aristocratic Manor Life - by both Julie and Luke (Earl and Countess of Sandwich)
Rewilding Mapperton - by Luke (with Julie and their son Nestor occasionally appearing)
I've watched a few things on their other channels and enjoyed them. I'm working my way through this series and I just love seeing the homes and the families.
