In this classic study Dr. Hull explores the historic background to the Dutch Quaker migration and William Penn's mission to Holland and Germany in 1677, which has been credited with touching off the large Dutch and German emigration to Pennsylvania. The movement began, of course, with the Krefelders' settlement led by Francis Daniel Pastorius at Germantown in 1683. Hull's scholarly study of the Dutch Quaker immigration to Pennsylvania (and incidentally the German Quaker immigration) contains a number of appendices that give the names of all the settlers in Germantown during the years 1683-1709, with brief genealogical notices, including place of origin. These settlers originated from places as diverse as Holland, Germany, Finland, Hungary, Silesia, Switzerland, Transylvania, and Great Britain. Other appendices include names from a 1693 tax list and names of Germantown residents naturalized in 1691 and 1709. The author gives both the Dutch and the German forms of the names cited.
