Fanny Knox was the daughter of an English diplomat and his aristocratic Siamese (Thai) wife. When she grew up, she had a number of suitors for her hand. One was Louis Leonowens, whose mother, Anna, worked at the royal court and wrote the books that inspired the novel Anna and the King of Siam, by Margaret Landon. He eventually married her sister Caroline. In addition, Si Suriyawongse, Regent for the young King Chulalongkorn, wanted Fanny to marry his grandson Nai Dee. Fanny, however, had fallen in love with another Siamese aristocrat, Phra Preecha, and married him in defiance of the Regent, who struck out at the young couple in his wrath. This is more of a biographical novel than a true biography.
