Even though the chronicle states that King Phetracha came from a Suphanburi commoner family, there is contemporary evidence that states his sister was King Narai’s first-ranked concubine, and in addition he was a close companion of Narai from childhood. 14 All this shows that Phetracha was
probably born into an aristocratic family of Ayutthaya, and it would be no surprise at all to find evidence that there is a line of the Prasat Thong dynasty, especially on the female side.
