Lorman ,
Yes, I have had some MICHE spellings also. Others have included: MEIHE, MIEHER, MOICHE, MIEHL, NEHA, NEMA, and probably variations of MEYER or MYER although none I know of in my direct line. Some of these were in an index but some were in actual documents.
I would be interested in the names of any of your MIEHE line that you know were in Macoupin County, Illinois.
