All meikeerthi references give date of ascension only
A clue would be to work backwards from Son of RJC - Rajadhiraja - he was crowned in 1018 ( Why was he crowned so early is a very interesting question) - work backwards giving avg age of 20 -25
Is there any reference that RRC and AK were born to the same mother and the mother being Malayanman Daughter?
I am aware that there is a inscription which syas Malayanman's Daughter performed a Sati when Sundra Chola died. But is the any inscription which says she was mother of AK and RRC?
