[3] Recent scholarship suggests that Arinjaya was the son of a Chera princess (hence a half-brother to prince Rajaditya).
[4] As per the Anbil plates of Sundara Chola, Arinjaya's mother was the daughter of Paluvettaraiyar, therein described as a Chera prince.
He was married to a Vaidumba princess of Eastern Chalukyas called Kalyani, who bore him Sundara Chola.
From an inscription found near Melpadi in north Tamil Nadu, we learn that Rajaraja Chola I erected a Siva temple called Arinjisvara as a tomb-shrine in memory of his grandfather Arinjaya who was also known as "Arrur tunjina devan".
Two of his wives Viman Kundaviyar and Kodai Pirattiyar seem to have survived him and made gifts to temples in Arinjaya's name during Parantaka II's reign.
