This book is a valuable addition to the series on genealogical references on the traditional Jewish population of Amsterdam sold on this site. This book is a survey of first names in Jewish deeds in Amsterdam from 1669 to 1850 and compares these with the matching first names in the civil deeds. In 1811 the Civil Registration was put into effect, which required all Dutch inhabitants to register their names. These names differed from those used within the Jewish community. This book is not only a valuable source to match the Jewish names to the civil names but also shows how traditional Jewish names became ‘gentrified’ in the course of the 19th century.
