Here's the script dialog from ROTJ. She was talking about her real Mom it seems.
BEGIN DIALOG
Luke turns and looks at her a long moment.
LUKE:Leia... do you remember your mother? Your real mother?
LEIA:Just a little bit. She died when I was very young.
LUKE:What do you remember?
LEIA:Just...images, really. Feelings.
LUKE:Tell me.
LEIA:(a little surprised at his insistence)She was very beautiful. Kind, but...sad
