O wait, that wouldn’t work either. Ep VI was about 30 years ago and Palpatine died then so he can’t be her father. Unless they are saying the sequels take place 19 years after VI. People age badly in these films. Obi Wan and Vader look pretty bad in IV-VI for only being 20 years after III. Maybe they’re gonna do that again and say Luke is only 19 years older and he looks like hell anyway.
It is canon that 30 years pass between ROTJ and TFA.
