I still contend that Owen is more minor. For one, Owen doesn't even appear. He's just briefly mentioned as Obi-Wan recalls his past in short chunks. He has no lines, and all of the sentences about him combined can be easily read in under ten seconds. Breha has appeared or been mentioned in numerous EU sources detailing many things about her, even her inability to conceive. And don't get me started on the General, whose Wookieepedia article is over one-fourth of a NaNo novel in length despite missing information from two sources.
