Dear Jentami- I found no full text listings for any of the names you gave me. I did find simple address listings for the following: John Koch, carpenter, Long Grove; Owen McMahon, farmer, Wauconda; Warren McMahon, farmer, Wauconda. I don't know if this provides any help for you. My family was in the Long grove area, so if John Koch is someone in your line, let me know and I can check other sources. Hope this helps. val peiler
