The marriage certificate shows another address for Fritz Neumann: Lettestraße 1.

A search of the address reveals that it is most likely his father’s, Ludwig Karl Franz Neumann address, as there is an F. Neumann, book printer, sometimes also typesetter, can be traced there from 1904:

This shows that Fritz Neumann’s father lived at Lettestraße 1 between 1904 and 1933 and worked as a typesetter between 1927 and 1931, otherwise as a printer. As Fritz Neumann had this address when he married, it can be assumed that he lived at home until 1925.
