Re 97 I've spent way too much time on this and can't come up with anything better than archeologist. It fits the definition pretty well with digs, then archeo meaning old/ancient (https://www.thefreedictionary.com/archeo-) , and logis translating from french to mean lodging/housing. However I really don't see why they would use an alternative but way less often used spelling here, when they don't need to fit it to a crossword grid. I don't think Egyptologist fits the definition as closely so have decided to go for archeologist unless someone has a brainwave (in which case I'll be very happy!)
