Dear Max and Barbara,
Last year they changed the organization of the Staatsarchive in
Niedersachsen.
There used to be seven almost independent state archives in the country,
Now they have got a president of the Niedersaechsisches Landesarchiv in
Hannover (Bernd Kappelhoff) and accordingly the email addresses were changed
as well. So the "staatsarchiv" in the address will not get you anywhere,
Rather use:
Hannover@nla.niedersachsen.de
Greetings from Diepholz
Falk (Liebezeit)
