I stumbled on an old genealogy book at Google books called "A Genealogical Record of the Descendants of Christian and Hans Meyer and Other Pioneers, by Rev. A. J. Fretz. It was published in 1896, and you can download it as a PDF.(search for Detweiler genealogy, Hans)
I found lots of people I was looking for, and you may also. I do not know what the quality of the research is, those familiar with this book, please comment for the rest of us.:-)Thanks!
