Are Uncle Owen and Obi-Wan brothers? Many readers have asked this question, and we addressed the issue as far back as Sept 2000 in this post. But the Official Site addressed the issue today in an update:

Is Obi-Wan Kenobi the brother of Owen Lars?

No. The two are from separate families with no connection through blood. Although a number of spin-off materials were published in 1983 and in subsequent years stating that the two characters were related, those materials were based on outdated and eventually discarded information.

Owen Lars is the son of Cliegg Lars. Obi-Wan's parents are unknown, and he has little to no connection to them having grown up in the Jedi Temple. He is aware of having a brother, but very little information about that sibling has ever been published.

This represents the first official confirmation that Cliegg Lars is Owen's father. For more info, visit the links above!
