While i was reading some inscription (ARNo.14, of 1920) Tirumalavadi, Udaiyarpalaiyam Taluk, Trichy , " Ilangon Pichchi, the senior queen of solapperumanar and daughter of Vallavaraiyar" , its talking about a gift of 10 kalanju of gold and a bronze lamp stand to the temple.
The lady mentioned above is daughter of Vandiyadevan, or some other?
As Swetha said in her mail, it belongs to Adhithya I. Ilangon pichi is his wife. Vallavaraiyar here is not our vandhiyathevan. Vallavaraiyar is his kulappeyar. This may be one of the ancestors of Vandhiyathevan. But it cannot be a Rashtrakuda king also. So far, it is not found that any Rashtrakuda king had the name Vallavaraiyar.
