The record match for Markus Sessel n the 1900 census that shows above has the same birth date and an date immigration of 1856. In both the 1870 and 1880 Census' there is a family living in Illinois with parents Elvessel and Caroline Sessel from Austria/Poland with the same birth dates as Hiel and Kayle. I wonder if that is the same family as they do not seem to appear in Krakow after the birth of Aron Beniamin??
