Information needs clarification

Hello,
Is there anyone in this group that can clarify the following information for me. Are these villages still in existence and is there a way to retrieve records for some of these camps etc. I thank you in advance. The information follows below:

Gr., between 10th July 1942 and 1st December 1943, employer not mentioned; was in DP Camp Mannheim on 18th October 1945, note: “Do not go back, since my husband was killed in a Soviet prison”; stayed in Hannover, Herrenhauser Kirchweg 5, on 28th September 1946 (birth of her daughter), resided: Hanover, Mockernstrabe, Camp; father: Andrae.
