Where does “biscuits” come from?

I notice this chain appears to show English words cycling back on themselves without progressing to earlier languages, which makes it impossible to write an accurate etymology. The chain needs to extend to the actual source language (likely Old French or Latin) to establish a proper origin. Could you verify the chain? A typical biscuit etymology would progress from English → Old French → Latin, but this chain only contains English entries.
