Of course we all know Sulakshana Khatri ji did a commendable job of portraying this character right from her grit as a queen down to the practical-but-will-spoil-you-to-death mommy to Kanha and Dau Bhaiya! 
Also did you guys notice, Sulakshana ji also plays the maid who informs King Ugrasena that Kans has murdered Keertimaan! đ˛
Okay so now down to business! đ
Parentage of Rohini:
I was confused since I read in an article that she was MB wale Vidur kaka's sister! đ
"Rohini, the descendent of the Puru clan, was the child of BâŹhlika, O King.
She was the foremost wife and darling of Anakadundubhi."
Paurav⌠is not exactly her name. It means that she descends in the Puru
dynasty. This is a popular (vyavahâŹra) genealogy. According to it Vidura is
the son of VicitravâŚrya and therefore a paurava. BâŹhlika (or BâŹhlâŚka) was
the brother of ÂŽantanu, who was the father of VicitravâŚrya. So BâŹhlika's
daughter could be vaguely, and popularly, called a "sister" of Vidura. I
guess she would be some sort of great cousin sister. Not a blood relation,
though.

I'm not sure if this finds a ground in any text/version?
Also, if this is not true then who are her parents? Was she a Yadava girl too? đ¤
