I am descended from Heinrich Adam Hermann. My brother was lookiing at the genealogy library in Salt Lake City Utah, and found a record of Johann Michael Hermann which I have posted some information about on the harman family forum (just do a google search). We do not read or speak german, so I cannot verify this record in german records. I have seen other postings of information from this record, on some harman/harmon family sites. Am posting this from my phone, so i apologise for not being able to remember the particulars of names and dates for you. Just input Johann's full name at the forum site, and it should pull up my post.
