Princess Yothathep was the only daughter and only child of
Narai and Queen Kasattri, one of his concubines. During her father's reign, she took over many duties about the palace when her mother died, such as caring for the ladies in-waiting and eunuchs. The highest honor she was a Royal master's degree. During the reign of King
Phetracha, she married the King and received the title of Left Consort, but she disapproved of King Phetracha because he had ordered his guards to kill her father's brothers. King Phetracha later married Princess Sisuphan, the Princess Yothathip, who was her father's sister, and promoted Princess Sisuphan to Right Consort. ==Death==
