#2-> Respected Sir, I think, there is a thread dedicated to Madurai Pushpavanam Iyer. in vidvans/vidhushi section. We can search in google and if there is no such thread, we can create one. and add the page from pasupathy's blog there. I suggest that you create separate threads each for Sri.Pushpavanam and Smt. Rajam. ( your grandfather and then your mother,as I understand). Both had distinct personalities and contributions. There are three or four tube links for the songs by Smt.Rajam.and I have some pages about Smt.Rajam. If you combine them, the chances of getting rare info about your grandfather's records will become slimmer. But, there should be a few as she was contemporary of Madurai Shanmugavadivu ( MS's mother and we have veena recital records by her).
As for moving this to the respective section, I think, any post stands a better chance of being noticed if a link is given in general discussion first and then more details in the respective section. (ex) you can say , I have posted a new entry in the thread (<thread name>" on <.....> . Better still , a google website page first and a link in rasikas will give more latitude about length, images, language etc.
I hope the MODs will approve.

wiki gives interesting information about Smt.Rajam ( daughter of Madurai Pushpavanam)
https://en.wikipedia.org/wiki/Rajam_Pushpavanam
SRUTHI magazine has brought out a specail issue honouring her, I understand.
(all thanks to google)
Sri.Swaminathan can initiate a new thread on Smt.Rajam, in musicians section. and give links to her songs in tube.
