The Duke owned Brodick Castle, where one of his regular summer visitors was a popular landscape painter George Hering, son of one of London's most successful bookbinders, Charles Hering Sr. George and his wife Caroline had lost their only child at the age of six and the Duke suggested that they adopt Marion.
Around 1880 the couple moved to 14 Langford Place, St John's Wood; at that time the house was named "Sunnyside" and included the present numbers 12 and 16.
The couple held numerous soirées and afternoon bazaars for friends and neighbours, and Sunnyside became a leading social centre for politicians and artists, including Sarah Bernhardt.
Unperturbed, she undertook the journey of 500 miles (800 kilometres) in about 7 weeks, with the poor nurse Ellen having to push the young child in a perambulator.
