Now printed in two volumes, this is the most important collection of Pennsylvania-German source materials to appear since the publication of Strassburger and Hinke's Pennsylvania German Pioneers over fifty years ago. Primarily a compilation of Reformed Church marriage records (including some records from Lutheran and Union churches), it provides documentation on some 50,000 persons of German origin or descent. Based on records in the collection formed by Dr. William J Hinke--records of approximately 100 churches in eastern Pennsylvania--the compiler has developed herein not merely a list of marriages but a genealogical record of the Pennsylvania Germans.
