If Liara's the shadow broker (and was an information broker), I believe she may have found out who her 'father' is. I don't remember any dialogue in ME2 about her discovering anything more on family (In fact, I don't remember her mentioning her family much at all in the second game). It's definitely possible that part of the reason her office and quarters are on Illium is because she wants to find out more but is shy about directly approaching her. It would definitely be a good investigation in the third game, especially if there was even more depth and history to discover.
