I wanted to add one of the Maetzolds from my group as well, in hopes that it might help you in your search somehow.
Carl Otto Leberecht Maetzold born 03/04/1860 at Hochenstein, died 1932 at Chemnitz. He is/was my Great-Grandfather on my Mother's side of the family.
I have some more Maetzolds to share from my Tree, if you think it might be along the lines of what you're looking for. Good luck in your search.
