Over the years, while working with a huge array of documentary sources relating to the different aspects of the Shoah, especially the biographical data of the victims, we have come across a large number of locations where particular events occurred or specific individuals found themselves before, during and after the Holocaust period. Most of these are inhabited places such as hamlets and villages, towns and cities; some are historical regions or administrative units; others are geographical areas such as forests, mountains and so on. <br> We have tried to document these locations, as far as possible, citing their names in different languages according to the time period, with varying spellings, as they appear in the sources we have studied. We are sharing this information here in the hope that you will find it interesting as well as useful for your further searches. At a later stage we will add information pertaining to persecution sites (camps, ghettos, murder sites, etc.).
