He was the son of King Samsenethai, who had ruled from 1373 to 1416, and his mother was said to be a palace slave.

Samsenethai
Samsenethai also called Oun Huan was the second king of Lan Xang, the son of Fa Ngum, whom he succeeded.
He ruled from 1372 until 1417.
The origin of the name Samsenethai is thought to be a reflection of the political and social upheaval occurring within the area at the time of his rule.
Samsenethai literally means "300,000 Thai," thus reflected the result of a census conducted in his reign.
It is unclear whether the census included the entire population or just men capable of bearing arms.
There is also discussion as to whether during this period, the terms "Thai" and "Lao" were interchangeable, whether the term "Lao" yet existed, or whether "Thai" was used in his name to refer to the fact that the census included all Tai groups.
Local Thai history records that Samsenethai's Mother was a high born lady of Ayuttaya (Siam - Thailand) and that she had brought Thai Ministers for the government of Lan Xiang
(Lan Chiang).
Also noteworthy, the flag adopted for Lan Xiang is a near copy of the flag of Ayuttaya.
