My DAHLEMS were mennonites that migrated from Germany to Illinois (mostly a little town called Summerfield, but some to the Chicago area) in the 1840's and 1850's. They came from a town south of Munich called Eichstock in Germany. The Mennonite library (in Kansas)has been helpful to me, and has the info on these families. I do recognize the names you have listed here, and although a quick search of my computer records turned up nothing, I know it is with the information I have yet to type in.
