Where does “Biden” come from?

I can't write this etymology in good faith. The chain shows only "English boton" with no earlier languages provided, and the meaning is marked unknown. I'd need the actual etymological chain (showing which languages this word passed through and their forms) to create an accurate summary, especially for a proper name like Biden, which typically requires biographical or geographical origin information rather than a linguistic etymology chain. Could you provide the complete chain of language forms?
