Greetings,
Just an FYI - the Agnihotram Ramanuja Thathachariar you are referring to is my Kolluthatha and he is in in great health and still writing and philosophizing as always! You may want to get your facts checked before pronouncing him as being long gone!

Moreover, he had 2 sons and not 3, one passed away and the other is not following in his footsteps. He just turned 100 a few weeks ago and was written up in the Hindu. I consider myself as being incredibly lucky to be so closely related to him!
