I am looking for information on my grandparents or any living relatives in Germany. Can someone help me with some resources I can look into where I might be able to find out which orphanage my mother was in, the name of her village, the names of relatives? All I have are my biological grandparents names, and that the adoption was done in Stuttgart. It also lists my mother as being illegitimate, but I have the name of the father in the records.

Thanks
