After hearing Lacey's testimony, I'm thinking, the title may come from the Preacher/Priest that 'saved her'. She said the Preacher's brother talked to her, and told her about God. If she wouldn't have heard him, she said she would have committed suicide. So, in short terms, "Uncle Bobby" may have been titled after the guy who talked to her, and [the song] could be about [Lacey] being reborn.
