Who are Amiens and Jacques?

It's impossible to say who "Amiens" and "Jacques" are without more context. Please provide more information, such as:

* Where did you encounter these names? (e.g., a book, a movie, a conversation, etc.)

* What was the context? (e.g., were they characters in a story, people you met, or just random names mentioned?)

With more information, I can help you figure out who these people are.
