Research: Wikipedia and Google give me the modern day town of Jussey, and including 'medieval' or 'history' in the search terms doesn't help much. I've read quite a bit about Charles the Bold's family tree, but that not helpful...
So. I'm trying to find out a bit more about a Burgundian nobleman, referred to as "Jussey", from a Mary Gentle novel. I don't think he's completely fictional. All I know of him from the novel is that he's fairly highly ranked in the army.
Was he a real person, or is there a real equivalent from that time period? What would be his title, and any chance of finding out his name?
Thanks in advance for any help you can give!
