Varananda Dhavaj, born Varananda Dhavaj Chudadhuj, was the son of Prince Chudadhuj Dharadilok and Mom Ravi Kayananda and grandson of King Chulalongkorn of Thailand. Although he was the only son of a senior Thai prince, he was disqualified from succession to the throne because his mother was not Prince Chudadhut's formal wife.
