Notes:

But I did find a couple of things.  One of them is the 1684 christening record of Johann Wolfgang Buchenröder, the stillborn son of Johann Buchenröder.  It is not completely transcribed but it is enough to show that he had been born in Sonnefeld, probably at the home of Stephan Thomæ, whose wife was one of the four godparents.  Christian Michael Buchenröder was the pastor of nearby Hellingen at that time but, as one of the other godparents, his wife was not listed as Barbara.  She was Margaretha.  But John Nicholas Kalb’s wife, Christina Rose Stegner, had Magaretha Barbara as her middle names so maybe Margaretha Bauer Buchenröder was really Margaretha Barbara Bauer Buchenröder.

The German transcription, still not finished : 8P
