Hello, you mentioned in your post that you wish to have contact with Manz family members from Virchow. I have the address of the leader of the "Heimatgruppe Virchow", which consists of a group of people who lived in Virchow. They could put you in touch with Manz family members. I also have the address of woman named Manz, age 86, who lived in Virchow. Contact me privately if you would like the information.
