No, I don't know anything about the Eickelmanns. Sorry.There was a Gerh. Eitelmann (along with 4 Franzens and others) who in 1848 was a charter member of St. John's in Addison twnp. (Bensonville). Maybe it is a misinterpretation of the spelling of the name? I have a pamphlet entitled "Johann Heinrich Franzen", written in German and published in 1893 as a tribute to him after his death. There is a translation of the first part which tells of the 1834 journey with his parents and 4 siblings. If you don't have it, you might want me to type that part and send it. The 2nd part I don't have translated because JHF isn't my ancestor and the rest looks to me like a funeral sermon. David Koss, 114 Dundee Ave, Barrington IL 60010, did a Franzen family tree and has researched many of the families from the Shale area.Don't know whether that would include the Eickelmanns, but he would be an excellent source to try.
