Yes, they did. Eventually, Leia contact her good friend Pooja Naberrie to discuss her mother so they definitely knew about Padmé Amidala and the fact she was their biological mother.
Did Luke and/or Leia ever find out the identity/name of their mother (Padmé) in either the Disney Canon or the expanded universe? In the Expanded Universe, yes, they finally find out after stumbling across recordings that Artoo had secretly made. Yes, in both.
Did you think Anakin Skywalker as a force ghost ever appeared to Luke Skywalker? Yes, in fact, I know. In Return of the Jedi, Anakin, as well as Yoda and Obi-Wan, appeared to Luke. Also, in the novel Shadow of the Sith, Anakin again appeared to Luke in a force vision.
Darth Vader's true identity as Anakin Skywalker was a highly guarded secret, known only to a select few individuals including Palpatine, Obi-Wan Kenobi, Luke, Han, Leia, R2-D2, C-3PO, Master Yoda, Bail Organa, Ahsoka Tano, Darth Maul, Grand Moff Tarkin, Grand Admiral Thrawn, Jocasta Nu, Ferren Barr, Verla, Reva, ...
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
How Luke Learned of Padme and Watched Her Death - Star Wars Explained
Why was Anakin too old but Luke wasn t?
In Star Wars, younglings were traditionally recruited into the Jedi Order from an early age — so young that 9-year-old Anakin Skywalker faced opposition as being too old to train. However, during the original trilogy, Yoda and Obi-Wan Kenobi resolved to train a 19-year-old Luke Skywalker.
In Star Wars Legends Leia was visited by the force ghost of her father Anakin Skywalker, the man who used to be Darth Vader. It wasn't a pleasant meeting as Leia was unable to forgive him for the things he'd done no matter how hard he begged, and it was the only time she saw him.
The realistic answer seems to be, yes, Anakin in his prime could have defeated Luke Skywalker (in the current canon) if they battled one-on-one. The main reason behind this is Luke's lack of formal Jedi training, at least when it comes to combat.
In order to keep the children safe from Vader, who was unaware of their births, it was decided that Luke would be taken to live with his uncle and aunt, Owen and Beru Lars, on Tatooine; meanwhile Leia was taken to Alderaan as the adopted child of Amidala's friend and colleague, Senator Bail Organa, and his wife, Queen ...
Leia's Force abilities and her lack of awareness of her true identity also contributed to Vader's inability to sense their familial connection. Vader's denial of Anakin Skywalker's legacy and his fear of getting hurt again prevented him from realizing the truth about his children until later in the original trilogy.
Anakin's Force Choke begins the series of injuries that ultimately leads to Padme's death, and convinces Obi-Wan to fight him. Despite this, when Anakin learns of Padme's death, his immediate reaction of grief and regret shatters everything in the lab with a powerful force shockwave.
Yes. In the book 'Tatooine Ghost', Leia learns of Anakin's life prior to his evolution into the Darth Vader personae. This revelation leads her to forgive him. She even named her third child in memory of her father.
He terrorized the galaxy at his masters side for over twenty years. Luke however did forgive his father, Anakin Skywalker. He knew he was manipulated by Sidious. That his father was a good person.
Leia was not using the Force or was currently Force-sensitive during her confrontation with Vader. She began training as a Jedi years later. All these reasons prove my point: Vader didn't know Leia was his daughter, and felt no presence of the Force in her, as she was not currently strong with the Force.
A Jedi needs to be a selfless servant, not an aggressive warrior. Yoda's teachings were focused on balance, both literally and figuratively. He wanted Luke to gain an understanding of the Force so that he would not be consumed with the prospects of combat.
Anakin Skywalker's birth mystery is solved - his mother, Shmi Skywalker, reveals that there was no father and she can't explain what happened. Qui-Gon Jinn believed that the Force itself created Anakin in Shmi's womb, making him the Chosen One who would bring balance to the Force.
Star Wars Explained - A long time ago, in a galaxy far, far, away... Why didn't Yoda train Anakin Skywalker if he really thought that he was "the chosen one"? Yoda didn't want Anakin trained. He considered him to be dangerous, full of fear which could potentially be catastrophic.
The sequence calls back to a similar scene in Revenge of the Sith, when Bail Organa orders Threepio's memory be erased to prevent him from sharing information about Anakin Skywalker's fall to the dark side.
Darth Vader acts like he doesn't even know C-3PO or R2D2. They were with him since he was a child. He did everything he could to forget his past. Also, his plating had been replaced many times, and protocol droids all look very similar.
Maybe R2-D2 didn't know Darth Vader was Luke's father because he didn't see Palpatine christening him Vader, or maybe he believed Anakin was dead because even Obi-Wan didn't know Anakin was alive.
