"Star Wars" Mystery: Who are Rey's parents?

(Possible spoilers ahead, although this is all just speculation.)

One of the big mysteries in the latest Star Wars movie, The Force Awakens, is about the lead character Rey's parentage. Director J.J. Abrams just gave a big clue (from CNN Money):

Speaking at New York's Tribeca Film Festival on Friday night, the director of "Star Wars: The Force Awakens, said that the parents of the film's heroine, Rey, were not in the hit Disney (DIS) film. 

"Rey's parents are not in Episode VII," Abrams said to the audience. "So I can't possibly at this moment tell you who they are."

This eliminates such iconic characters as Luke Skywalker, Leia Organa, Han Solo, or even Darth Vader/Anakin Skywalker (his mask made an appearance, plus he is unlikely after the events of Star Wars III). So who is left?

1. New characters. Her parents might be characters that haven't been introduced. I tend to doubt this only because it would be a big letdown. In most Star Wars canon, the Force tends to travel in certain bloodlines.

2. Obi-Wan Kenobi. This is one of the favorite possibilities among people speculating. He is a much-beloved character, although such a possibility would be in violation of his Jedi training, as Jedi are not supposed to give into passion. It leads to the Dark Side. But it may have been a youthful indiscretion?

On top of this, the fact she grew up on the desert planet Jakku gives a second answer to why Kenobi was on Tatooine, also a desert planet. Perhaps Kenobi knew his daughter had been left on a desert planet, and he chose Tatooine mistakenly? However, this is also why I tend to doubt this idea: Wouldn't a Jedi master like Kenobi have sensed his own Force-strong daughter?

3. Darth Sidious aka Emperor Palpatine. Not much is known about the Emperor's personal relations, so this is plausible, albeit not particularly satisfying. However, it does carry with it some irony. Anakin's son was hidden on a desert planet, and the Emperor's daughter could also be hidden on one.

4. Boba Fett. This makes sense because he is one of the most beloved of the minor Star Wars characters. He was a vengeful bounty hunter, whose story intertwines nicely with the main story of the Star Wars universe. This one is my pick, as it explains why he was popping up repeatedly during the original series.

5. Another minor Jedi or Sith character. Count Dooku? Darth Maul? Qui-Gon Jinn? Mace Windu? Keep in mind, if you go back to the characters who died in Episodes 1-III, then you are probably calling Rey their granddaughter. Not impossible, but this seems like an uninteresting stretch. I would rate this as highly improbable.
