Napier’s grandfather was Captain Napier Sturt, the third and final Baron Alington, and her aunt Charlotte Mosley – sister of her father, Napier – was married to Oswald Alexander Mosley, son of the leader of the British Union of Fascists and Diana Mitford.
Mary and Toby went on to have six children; five daughters and one son, Napier Anthony Sturt Marten, who became heir to the family’s £115 million fortune and was famously a Page to Queen Elizabeth II.
Constance’s father Napier – who made headlines for his own disappearing act nearly two decades ago and had long been something of a mystery in the family – back then spoke of his “immense relief” that she has been found.
The parallels between the lives of aristocrat Constance Marten, 35, and her father Napier, 63 – a former page to the late Queen – are not difficult to come by.
Napier’s mother, Mary Anna Marten, was a British Museum trustee whose godmother was the late Queen Mother and who played with Princess Margaret as a child.
