From the introduction: Names are a valuable source of information. They can indicate gender, marital status, birthplace, nationality, ethnicity, religion, and position within a family or even within a society. However, naming practices vary enormously across the globe. The aim of this guide is to identify the knowledge that can be gained from names about their holders and to help overcome difficulties that are commonly encountered with names of foreign origin.
...The sections of the guide are governed by nationality and/or ethnicity, depending on the influencing factor upon the naming practice, such as religion, language or geography.
