Sorry, but I do not have any new information for you. I do have a great grandmother Mary Korinek who married a John Peter Hohenadel in Cook County, IL in 1878. As a geneological neophyte, I'm luck to have that information. With the Chicago Fire destroying records prior to 1871, the search will be difficult. The mention of Berwyn, IL struck a chord. I grew up in Oak Park, an adjacent suburb. If you have any information on Korinek's please drop be a byte.
