VEERAVAN MADEVI COMMITTED SATI WHEN RAJENDRA I PASSED AWAY.
Sons ::
Rahadhirajan I (1018 - 1056 ) co ruled with RjC Rajendra II - 1051 - 1063 Veera Rajendra - 1063 - 1070.
Another view point is that :: Sundara Chola Pandian @ Mummudi chola pandian also supposedly son of Rajendra I. He controlled that part of province from Madurai.
KARANDAI TAMIL SANGAM Souvenir mentioned following sons also totalling to six ::
Vikrama Chola pandian
Parakrma chola pandian
The view point is from Meykeerthi of Rajendra II - "Thirumaadhu puviyenum .. " -
some detailed study leads to a speculation that Sundara Chola Pandian @ Mummudi chola Pandian @ RAJA MAHENDRAN was son of RjC I !!
Daughters :
ARUMOZHI NANGAI gave grants to THIRUMZAHAPADI !!
AMMANGA DEVI married RRC's daughter Kundavi's son Rajaraja Narendran - who later became to be known as Kulothunga I ! She out lived Kulothunga I .. and inscription of Kulothunga III also mentions of her !!
HI Sps overlapping names between wives of different kings may mean the same families gave daughters to the kings. i think both rrc and rjc took wives from pazhuvur and kodumbalur.
As I have been looking at, most of them are marriages towards political balancing.
Thirubuvanamadevi @ Bhuvanamadevi @ Olagamadevi names mostly related to Crown Queen and the immediate next one.
Panchavanmadevi appears to be very CHOSEN name - more likely a Queen Scholar in Classical Arts and Dance - as atleast RRC's Panchavanmadevi also was known as Nakkan Thillai azhagiyar !
Actually there was a Panchavanmadevi Queen to Uthama chola Rajaraja chola and Rajendra I !!
Re Thiruvaiyaru - the Vadakailasam is supposedly done by danthisakthividangi w/o RRC.
Thenkailasam by RjC' wife... more likely Panchavanmadevi.
( I also remember to have read somewhere that it was built by Sembianmadevi... the author might have erred ).
Put "Thiruvaiyaru " in search - you will find very very interesting informations.. even recently (during Mrs. Shoba's visit and her husband "Gentleman" Mr. Ramakrishnan's blog immediately come to my mind..
There are atleast a member from Thiruvaiyaru (Narendran ?) .. and Satheesh - from Thanjavur has discussed vividly in his blog too.
