If I recall correctly the Portuguese term was the original etymology of all the "marmalades" in other languages. The French changed the meaning of the world by extension from "quince cheese" to "citrus preserve", and then every other languages just took the French meaning. For instance, in Italian _legally_ "marmellata" should be applied only to citrus preserves, but in common usage it came to be used to refer to every kind of jam (the correct term being "confettura", which is rarely used). In German if I recall correctly "Marmelade" just means "jam".
