Princess Suvadhana (Thai: สุวัทนา;, 15 April 1906 – 10 October 1985) Her Royal Highness Princess Suvadhana She was the royal consort of King Vajiravudh (or Rama VI) of Siam. Her original name was Khrueakaeo Abhayavongsa (Thai: เครือแก้ว อภัยวงศ์;). She was born a commoner; her father was Lord Abhayabhupesa (Lueam Abhayavongsa) and her mother was Ms. Lek Bunnag.
Khrueakaeo first met King Vajiravudh in 1924 during a dramatic production, in which they both acted. Soon after, Khrueakaeo was renamed Suvadhana and elevated to the rank of a minor consort. Later that same year they were married at the Grand Palace in Bangkok. Although King Vajiravudh initiated many Siamese nationalistic policies of the 1920s, his queen Suvadhana was a daughter of the Thai governor of Phratabong province (Battambang). Suvadhana's grand aunt, Khun Chom Iem Busba, was the wife of King Norodom I of Cambodia.[1] [2]
When Suvadhana became pregnant in 1925, the King elevated her rank to that of Phra Nang Chao Suvadhana (HRH Princess Suvadhana, Princess Consort of Siam; Thai: พระนางเจ้าสุวัทนา พระวรราชเทวี). Not soon after the King fell gravely ill, on the 25 November 1925, Suvadhana gave birth to a daughter, Princess Bejaratana Rajasuda.

In 1938, as war loomed, the Princess and her daughter emigrated to the United Kingdom, following the example of Prajadhipok who went in exile there in 1935. First she lived at Fairhill Villa in Camberley, Surrey, she later moved to Brighton. During the Second World War the Princess volunteered for the British Red Cross, donating winter clothes and other equipments to British soldiers; she later received a letter of recommendation from the organization. She would spend 22 years in England, she made her own living by investing in stocks and bonds; living a comfortable lifestyle with Thai servants.
The Princess and her daughter returned to Thailand permanently in 1957. They bought some land on Sukhumvit Road Soi 38, and build the Ruenruedi Villa Palace.

Suvadhana died at Siriraj Hospital on the 10 October 1985 at the age of 79, her funeral was presided over by King Bhumibol Adulyadej (or Rama IX) and Queen Sirikit.
