For Noneofthis: another reference by J Smolka, The role of the works of R J Boscovich in Bohemian lands (Czech), Acta Hist. Rerum Natur. Nec Non Tech. 11 (1967), 117-133. that refers to Roger Boscovic himself as Croat.  So you can't accuse me being biased...  We can add this one to your claim.  The research continues...  We will however, in the end, need a way to classify this man properly, please see above my extrapolation about Croat/Serb ethnicity issues prior to 19C, especially in Dalmatia, Dubrovnik, Bosnia, Montenegro etc.  Boismortier
