*It is not fully known where on the family tree they belong, so I used my best guess.

**Den Solo was most likely the public identity of Dalla the Black, a notorious pirate and probable heir to the Corellian throne.

***According to the Star Wars: Darth Plagueis novel: Darth Plagueis, and his apprentice, Darth Sidious, committed an act in direct violation to the nature of the Force.
  To further the Grand Plan, the two Sith had attempted to will a being of their own design into creation, pouring their malicious intent into waves through the Force
  to the countless midi-chlorians spread across the galaxy. But the experiment appeared unfruitful, and perhaps he was created by the Force as a reaction to the Sith Alchemy.
  Also in the Revenge of the Sith Screenplay, Palpatine says to Anakin, "I have waited all these years for you to fulfill your destiny [...] I arranged for your conception.
  I used the power of the force to will the midichlorians to start the cell divisions that created you." Of course Palpatine could have been lying.


****Pallopides was identified as the great-niece of Emperor Palpatine in the Dark Empire Sourcebook,
  but in the novel, Star Wars: Darth Plagueis, it is revealed that Palpatine murdered his younger siblings;
  it was also revealed that Cosinga had a mistress, this extramarital affair leaves open the possibility that the Pallopides claim may be valid.
