Since there doesn't appear to be a "Nova Vesta", I'm assuming it's "Nova Ves" which isn't much help, because there are about a dozen in Moravia alone. I looked through most of them in the Aug 1883-1884 time frame and did not find him.
Has anyone found the actual ship's record? Again, I find many that could fit, but none with the immigration date stated. Records after 1900 had more information, such as where they came from, etc.
