I'll look for more, but I thought this resource would be a beginning. These companies were would registered within the county and state of MO with the owners' names because they paid taxes. You have begun a difficult task concerning a relationship between work and the medical health of those who worked in those mines. Perhaps you might be able to find some specific facts within it so as to pinpoint the exact areas within MO. http://minerals.usgs.gov/minerals/pubs/commodity/lead/380498.pdf Rhonda Warmack Houston
