Where does “Bronson” come from?

I appreciate the detailed rules, but I need to flag an issue: the chain provided doesn't support an etymology for "Bronson" (a modern English surname/given name). The chain traces back to Proto-Indo-European roots for "sun," which doesn't connect to "Bronson." To write an accurate one-sentence etymology per your rules, I would need a chain that actually leads to "Bronson"—for example, something showing it derives from "bron" + "son," or its actual historical origin. Could you provide the correct etymological chain for Bronson, or clarify if this was a test of whether I'd invent unsupported connections?
