Dear Sir, Thanks for the comilation. If you can add one more Point: Thirumazhisai Alwar was earlier the Siddar Siva Vakkiyar. He converted from Saivisam to Vaishnavisam by Pei Alwar - According to Guruparampara. If this info is added, that will be helpful to curb the various futile discussions on why Sivavakkiyars songs are not included in 12 Thirumurais and various reasons attributed to it.
