Hello Sam,
My parents bought Holly Hill House in 1970 and an Elsie Loverage looked after the house for us, for the gardens my father employed a selection of local farm-workers who'd been laid off work; we had no chauffeur.
Audrey Trollope, from whom my parents bought the house, had bought it in about 1967. I knew her and she had no driver but as for gardeners, I really don't know.
Elsie had worked in the house since about 1940 and knew absolutely everything about it and the people who had lived and worked there, she lived in a cottage half-way down the drive and may still be living there. Elsie must now be about eighty-six, if still alive.
Good luck,
Nicholas
