James, Looking through the 1920 census I find a lot of Croatians worked at the Meat packing plant. I think this was Krey, my grandfather had worked there. There was quite a few working for the Railroad and some in the shoe business. I don't know if St. Louis is like the shoe capital or what but most of my family German , Croatian, Irish, and English wee in the shoe business one form of another, lol Michelle
