Most were good, with a few exceptions.Æneas sounds kinda pretentious, mostly because of the Æ. Why not regular Aeneas?While I like Lucas, it sounds like it would be mispronounced in Croatia with that spelling.
Going by traditional Croatian pronunciation rules Lucas and Lukas would not be pronounced the same. But people are used to seeing English names now and usually wouldn't make mistakes (especially since Lukas and Luka are very popular names now).
