Roy family confusion

Can someone explain the relations of Roy family? On wikipedia it's written something else and in episode, it is something else.

On Wikipedia, they said Ananya is Amir and Nargis (who is she and in which episode is she shown?) daughter but in the episodes, MJ addresses Sudhir as her father and Amir is his employee-friend from what I understand.

On Wikipedia, Dr Diya have a son called Typsy but in which episode is he shown? From what I understand, she is MJ second wife and have no other children.

Please clear this thing

As for now, telling how much I know.

Antara - MJ's wife

Ananya - MJ's friend Sudhir's daughter, Rudra's friend

Diya - Someone close to Roy family, Rishi calls her aunt.

Rudra - MJ & Antara's son

Rishi - MJ & Antara's son

Amir - his employee & friend

Dadi - MJ's mother

Wikipedia is mess. They made it even before the show aired ! So, don't look at that.
