Does RK know Madhu was born in the studio?

The CV's did show that Balraj Chaudhury managed to trace Madhu from newspaper articles printed of Madhu's birth at the studio, as Madhu's name and Padmini's face were on the articles. However, they didn't show that RK knows about this. But when Padmini came to the studio once before when Rishbala were just married he introduced her and listed down how many films Padmini had acted in as junior artist plus the length of time she was now in retirement for...so what I'm trying to say is he could know about where she was born too. He has been obsessed with her for a long time since he met her, to gather so much info about her and her family.
