[Star Wars] What was Luke told about his mother? What was Leia told about her father?
gpt
Owen discouraged any conversation about his parents.  Luke was more interested in his father and it's clear that Owen lied about him about Anakin.

We don't know how much Leah asked about her parents.  We know she knows she is adopted (Bail likely told her - probably not much of a secret anyhow). He likely asked about them but Bail knew that she couldn't find out so they likely told her that her father died during the clone wars and her mother knew Bail from the Senate and placed Leiah in her care before dying.

Both Bail and Owen were told by Kenobi to keep them a secret.

Eventually, they found out the truth of course.
