Kashemsri Subhayok

Prince Kashemsri Subhayok, the Prince Divakaravongse Pravati [RTGS: Kasemsi Supphayok, the Prince Thiwakon Wongprawat] (พระเจ้าบรมวงศ์เธอ พระองค์เจ้าเกษมศรีศุภโยค กรมหมื่นทิวากรวงศ์ประวัติ), was the thirtieth child of King Rama IV of Thailand, and the fourth child born to Chao Chom Manda Chan, a royal consort of the King, born on 17 August 1857. He was known for his artistic, poetic, and architectural contributions, and served as a privy councillor during the reign of his brother King Chulalongkorn.

King Rama V elevated his royal rank to Kromma Muen (กรมหมื่น), and granted him the titular name of Divakaravongse Pravati (ทิวากรวงศ์ประวัติ) in 1896.

He is the founder of the House of Kashemsri (ราชสกุลเกษมศรี)

Prince Kashemsri Subhayok died in the reign of King Rama VI, on 3 January 1915 at the age of 57 due to illness. King Vajiravudh (Rama VI) presided over the initial funeral rites, before ordering that the prince's body be kept in a ceremonial urn for one year of prayer as was customary for Siamese royals of higher rank. The king also decreed that government officials would observe the funeral of the late prince by wearing mourning attire for fifteen days. After the rites concluded, King Vajiravudh presided over the prince's cremation at Wat Benchamabophit on 11 June 1916. The prince's remains were interred within the royal cloisters surrounding the chedi of Wat Makut Kasattriyaram, the temple of his father King Mongkut. Since then, many members of the House of Kashemsri have chosen to have their remains interred within Wat Makut as well.
