His Royal Highness Prince Remigius Jerry Kanagarajah was born to an Aristocratic family in Sri Lanka on 1 October 1964, the youngest son of the late Ilavarasi Maheswary Marina Antoinette Kanagarajah and the late Ilavarasan Thambirajah Mervin Anthony Kanagarajah. His Ancestors hailed from India, Jaffna (Sri Lanka) and Malaysia. He also lived in many countries other than Sri Lanka. Even as the youngest of five children, he was brought up with strict rules and regulations of his Royal descent. He is a Descendant of the Royal Family of Jaffna. The origin of his family's Royal abode is "Cankili Thoppu" in Nallur, the Palace of the Kings of Jaffna.
The Royal Family of Jaffna had ruled the Kingdom of Jaffna for many years. It was a well established Kingdom during its reign in Jaffna and it existed for 403 years. Unfortunately, the Portuguese settlers invaded the Kingdom and on 11 February 1621, the Kingdom of Jaffna fell into the hands of the Portuguese. Those of Royal decent were taken to Colombo and then to Goa and were given the choice of either life through conversion to Catholicism or been put to death. Some who had accepted the Church for guidance were either allowed to return to Jaffna or were interned in monasteries. On 4 February 1948, Sri Lanka gained Independence from British colonial rule. On 22 May 1972, a new constitution was adopted and Ceylon was renamed Sri Lanka. All ties to Britain were severed and Sri Lanka was declared a Republic.

Prince Remigius Kanagarajah is also a member of The International Monarchist League in London as well as the Southeast Asia Imperial and Royal League, which promotes friendship between Royal Families of Southeast Asia.
