King Hiranyavarman was the father of King Dharanindravarman I (r. 1107–1113) and King Jayavarman VI (r. 1082-1107). He never claimed that his dynasty has any link to the King Suryavarman I’s dynasty nor to any other lines of Khmer kings. However, his great-grandson, Dharanindravarman II claimed the throne through the marriage with Sri Jayarajacudamani, granddaughter of King Suryavarman I.^[1]

He was named after Hiranyavarman, a son of Somasaman and a daughter of King Viravarman.^[1]
