This volume of the Worthington Families of the Seventeenth Century covers the lines in Lancashire but also elsewhere in the world where their ancestry has been traced back to Lancashire; three in Lincolnshire, one in Warwickshire, one in Middlesex and one in Maryland, America. Volume 2 will cover the remaining lines. Over a period of more than ten years members of the 17th Century Project researched original written documents, microfilms, microfiche images and online databases which resulted in the accumulation of over two thousand eight hundred references to Worthingtons from 1560 to 1730. These were entered into ten volumes of one hundred pages each as a Register of Worthington References. From these references over sixty pedigrees were produced of which thirty two are covered in this volume. Each chapter deals with one pedigree and each person within the pedigree has an individual article devoted to them. In addition to the pedigrees there are seventy six illustrations. As an academic reference work this book is commended to the leading genealogical libraries of the world and to individuals who are researching their Worthington ancestors.
