Dormé (the handmaiden that was played by Rose Byrne in Attack of the Clones) is actually Anakin’s half-sister. Dormé’s father lived on Tatooine for some years, and had a romance with Shmi before she was captured and sold into slavery. The Hutts captured her shortly after she gave birth to Dormé, but the newborn Dormé and her father managed to escape without being captured by the Hutts, and fled to Naboo. Shmi never saw Dormé and her father again, and the Force impregnated her two years after she was sold as a slave to Watto. She never tried to look for Dormé and her father even after she was freed from slavery, because she knew that both of them had a completely new life at that point, and she didn’t want to mess up their lives. And Dormé never knew that she was adopted, because both her father and her adoptive mother never told her. So… yeah, one of Padmé’s handmaidens was actually related to Anakin, and neither of them ever knew that.
