Hello Daniella,

The book Rodney mentioned, Die Ausbürgerung deutscher Staatsangehoriger 1933-1945, is organized by the date the name appeared in the Reichsanzeiger.  Once you have the date searching the digital version is a lot easier.

If the people you seek were living in Germany, and thus listed in this book, send an email to reference@... with the full names of the people and mention you want us to specifically check this book.
