Princess Anne was the first child of Queen Elizabeth to be allowed not only to tie her life to a commoner, but also to divorce him for marriage to another man of inferior blood. Anna was married to sportsman Mark Phillips for 19 years. In 1977, they had their firstborn son Peter, and four years after that their daughter Zara was born. It was after this that Anna's relationship with her husband began to deteriorate and they decided to live separately. In 1989, The Sun published Princess Anne's love letters, which were obtained illegally. They were written by the Queen's assistant Timothy Laurence. After the publication of the letters, the relationship between Mark and Anna became absolutely unbearable, so the couple decided to separate. However, with an official divorce they were slow. And in 1991, an art teacher from New Zealand named Heather Tonkin said that Captain Phillips is the father of her five-year-old daughter, which was later confirmed by DNA expertise. Princess Anne then filed for divorce. It was finalised on 23 April 1992. In December of the same year, the Princess married Timothy Laurence.
