I have a 1911 address book from Zwittau and there are a lot of Haupt listed. I also was there last month looking for relative addresses. Mine were Demel and Liebhafsky.
I will try to send a copy of the address page if I can figure it out.
I know your post was some time back.
My personal email is email@example.com
. I live in Texas.
I hope I can be of help.
Seems like photo can be attached. Have address books also 1922, 1929, 1935 and 1940. All my relatives were removed after WW2
