Her husband Thihathu, Viceroy of Prome, is known in Burmese history for assassinating his father King Narathihapate of Pagan, and attempting to take over the Pagan throne.

Narathihapate
Narathihapate (also Sithu IV of Pagan; 23 April 1238 – 1 July 1287) was the last king of the Pagan Empire who reigned from 1256 to 1287.
The king is known in Burmese history as the "Taruk-Pyay Minthe King who Fled from the Taruk [Mongols]") for his flight from Pagan (Bagan) to Lower Burma in 1285 during the first Mongol invasion (1277–87) of the kingdom.
He eventually submitted to Kublai Khan, founder of the Yuan dynasty in January 1287 in exchange for a Mongol withdrawal from northern Burma.
But when the king was assassinated six months later by his son Thihathu, the Viceroy of Prome, the 250-year-old Pagan Empire broke apart into multiple petty states.
The political fragmentation of the Irrawaddy valley and its periphery would last for another 250 years until the mid-16th century.
The king is unkindly remembered in the royal chronicles, which in addition to calling a cowardly king who fled from the invaders, also call him "an ogre" and "glutton" who was "great in wrath, haughtiness and envy, exceeding covetous and ambitious."
According to scholarship, he was certainly an ineffective ruler but unfairly scapegoated by the chronicles for the fall of the empire, whose decline predated his reign, and in fact had been "more prolonged and agonized".
