Is There a dunnage and Cheese Connection?
Etymologists don't know the exact origin of dunnage. Some have pointed out the similarity of the word to dünne twige, a Low German term meaning "brushwood," but no one has ever proven the two are related. Others have speculated that it derives from Dunlop, the name of a famous cheese-making town in Scotland; however, neither the town nor the cheese has any connection to dunnage. Truth be told, though dunnage has been with us since the 15th century, its etymological history remains a mystery.
