Address for Northwest Germany

Hi,
  Two people lately have ask for addresses to Archives etc. in the Westfalen
area. I have corresponded with 2 different towns, one is the town of
Witten, the other is Detmold. They are not to far from Koln. These would
be southeast of Koln. Witten is on the Ruhl River.
  The addresses: jochen.kompernass@stadt-witten.de

                                gabriele.hamann@stadt-nrw.de
  I received a correspondence that they have information on my family and I
sent the letter and money yesterday! I am excited, hope this will help
someone else.
