The Genealogical Society of Southern Illinois - GSSI - would have copies of this. They have a website that lists all of their publications. If you write the society a letter requesting a look up you could find out if your family is in there. I usually enclose a check for $15 for a look up and that helps supports the society. It may not be necessary to do that but I know our local Society in California charges that much for look ups and I try to do the same for other societies when requesting information. Jo
