Hi,
Thats an old German script (19th century) list of names, professions and addresses.
Its either from a public addressbook or from the advertisment section of period newspaper. I see a tailor, a language teacher and food merchant (cheese, flour, yeast).
Obviously repurposed as glue underpaper for the pictures.
No hidden meaning, sorry.
If it is you family I think they read a Berlin newspaper since I can read a Köpenicker Strasse and a Jacobstrasse. Both of these are very close together in Central Berlin.
No hidden meanings imho, sorry.
Namxat
