Visit to Rotenburg(Wumme)

[fbsearcher]

Hello,
My wife's family name is Sandman and we have traced her line to Rotenburg(Wumme).  We are now driving in Europe and we shall visit the area at the end of June.  We hope to find some records and take some photos of the locations in which her ancestors lived.  Is there anyone who can advise us on how to proceed?  In particular, we are hoping to find a local family history addict who can talk to us (in English, please) about the area and its records.  Any further thoughts from the forum most gratefully welcomed.
