I've stumbled across this family a number of times. I'm apparently descended from this line, but it hasn't been proven yet.
There are merges pending on Weltin Fleischmann and his son, Cyriacus, but I don't feel well-versed enough in Germany genealogy to put these through, and I was hoping the German Roots folks, specifically the Thuringia Project, would like to take over.
The descendants of this family need a lot of work. There are duplicates as well as descendants appearing in the wrong generations, etc. I'm happy to do what I can to facilitate any merges, but I don't have much experience with German research.
