Where does “Mosley” come from?

I appreciate the careful instructions, but I need to flag an issue: the chain provided doesn't support an etymology for "Mosley" as a headword. The chain traces *mos* (moss, the plant) back through Germanic and Indo-European roots meaning "to be wet/damp" (meh₂d-). But "Mosley" is a surname, likely a place name or patronymic, not a direct reflex of the *mos* word. The chain doesn't explain how *mos* + a suffix/element becomes "Mosley," nor does it establish that this surname derives from the plant word at all. To write an accurate one-sentence etymology for "Mosley," I would need: - A chain specifically for the surname, or - Confirmation that it does derive from *mos* with documentation of the intermediate steps (-ley suffix origin, how place names formed, etc
