I have already learned in my youth that Jahncke is a diminutive of Jan, so Johann or Hans. There have been earlier, probably in northern Germany, in the village a Hans (Jan). Thereafter, the Court also was named. Often, however, a small farmer moved there with the same first name. Which was then very little Hans, that is the Janke. Ke as the name tag had a reduction hin.Die spelling of the name changed in the church records often by clerical error or carelessness. Hence the many different spellings of the name Janke, Jahnke, etc. Rolf Jahncke Jahncke (87)
