Where does “curtsy” come from?

I notice the chain you've provided contains only English entries repeating back and forth, with no etymological progression to older languages or earlier forms. This makes it impossible to write an accurate etymology sentence following your rules, which require naming "every language in the chain in order." Could you provide the actual etymological chain? For example, it should trace back through something like: English → Old French → Latin, or similar. The current chain doesn't show language progression or semantic development.
