Biography.
Nak was born in 1737 to a local patron of Bang Chang named Thong and his wife San. She was then married to Thong Duang the "Luang Yokkrabat" of Ratchaburi (future Rama I) around 1760 to avoid being taken as a court lady to King Ekathat. She having three sons and seven daughters to Thong Duang. Her sister, Nuan, was married to Bunnag – the progenitor of Bunnag family.
Thong Duang was granted the title "Somdet Chao Phraya" by King Taksin in 1776. In 1779, the "Somdet Chao Phraya" went on his campaigns against Vientiane and took a daughter of King Suriyavong of Vientiane as his concubine – Kamwaen. Kam Waen became "Somdet Chao Phraya"'s favorite much to the dismay of Nak. One day, she beat Kam Waen with a wooden stick and Kam Waen ran for the "Somdet Chao Phraya". The "Somdet Chao Phraya" was enraged with the incident and threatened to murder Nak with a sword, only with the help of her son Chim (the future Rama II) was Nak able to flee to the Thonburi Palace to live with her daughter Chimyai (concubine to King Taksin).
After the incident, Nak and the king had never came into reconciliation. Lady Nak stayed in the Thonburi Palace with her daughter and after her death in 1779 took care of her children including Prince Kasatranuchit. The "Somdet Chao Phraya" became a monarch in 1782 and most of Taksin's sons were executed except for Prince Kasatranuchit who was his own grandson. Lady Nak and her grandsons moved to her former resident and had never received any royal titles. She occasionally went to the Grand Palace to visit her daughters.
