Dalla Solo

"... the history texts describe him more accurately as a kidnapper and a pirate."

- See-Threepio

Dalla Solo, also known as Dalla Suul or Dalla the Black, was a human male of Corellian ancestry who became a notorious pirate around the time of the Clone Wars. He was sometimes said to have been the rightful heir to the Corellian throne, and the grandfather of Han Solo, but it is not clear whether either of these claims was correct.

Dalla was born on Duro, the son of Korol Solo, who claimed to be the descendant of Berethon e Solo, and who was executed for his pretentions to the throne. Korol's son assumed the pseudonym Dalla Suul to disguise his identity, and carved out a career as a pirate and kidnapper, earning the nickname "Dalla the Black". His illegitimate daughter was the mother of Threkin Horm, but Han Solo's father, Jonash Solo, was said to have been his firstborn, and legitimate, son.

If Dalla the Black was indeed Han Solo's grandfather, he was probably also the man known in the Corellian system as Den Solo, who disappeared with his infant son during a pirate raid on Tralus, and whose daughter Tiion Solo became the mother of Thrackan Sal-Solo.

Behind the scenes
In The Courtship of Princess Leia, See-Threepio says that Dalla was born "nearly sixty years" before 8 ABY; but for him to be Han Solo's grandfather with a birth date of around 50 BBY, both he and his son would have had to have sired children in their early teens.

However, this is one of a number of comparable instances where Corellians' ages seem implausibly young: some fans believe that these statements should be retconned as references to a longer calendar year used in the Corellian system.
