I am trying to find immigration records for my great-great grandfather. His name was John Briskey (alt spelling Brisky, Briski, Briske) and it's possible he went by Ivan. He was born around 1866-67 in Croatia, which at the time would have been considered part of Austria. According to the 1910 & 1920 census, he arrived in either 1892 or 1893. I can find lots of people with the same name and origin, but I can find any arrivals that coincide with the arrival date.
I know that by 1910 he was living in Calumet Michigan and was already naturalized, but I can't find any records predating that.
