At the suggestion of a relative, the young Sangwan was sent to live with Chan Saeng-xuto, another relative and a nanny to Princess Valaya Alongkorn, the Princess of Petchaburi, daughter of King Chulalongkorn (Rama V) and Queen Savang Vadhana (later Queen Sri Savarindira, the Queen Grandmother). At the age of seven, that the young Sangwan found herself presented to the royal court in the manner deemed proper for young Thai girls with the right connections and opportunities. Her only duty at that time was to present herself at a twice-daily audience with the Princess – when she woke up and again in the evening. Every now and then, she would join the Princess’ entourage when she went for an audience with her mother, Queen Savang Vadhana at Suan Hongsa Royal Villa, in the grounds of Dusit Palace.
