At sixty-years old in 1912, he had five children by his first wife and two by his second wife. He was also the prime minister of Great Britain at a critical time - just two years before the outbreak of World War One.
Venetia Stanley was only twenty-two-years old and the best friend of Asquith's daughter, Violet, who later became Lady Violet Bonham Carter. Between 1912 and 1915, Asquith wrote more than five hundred passionate love letters to Venetia.
