I want to know the answer to the following question:
What were the names given to the various dialects predating the 19th century?
All the background I'm provided with is that "Croatian linguist Dalibor Brozović advocated the term Serbo-Croatian as late as 1988, claiming that in an analogy with Indo-European, Serbo-Croatian does not only name the two components of the same language, but simply charts the limits of the region in which it is spoken and includes everything between the limits (‘Bosnian’ and ‘Montenegrin’).". Is that enough to answer the question?
Answer: no
