The author traces his Lashbrook ancestors back seven generations and his Taylor ancestors back through eight generations. William Lashbrooke, the author's 5th Great-grandfather who was born on 17 October 1717 in Meeth in Devon, England immigrated to the U.S. from Devonshire in 1738 as a bonded passenger/criminal on a ship named "Forward." Isaac Taylor, the author's 6th Great-grandfather who was born on 8 October 1710 in County Antrim, Northern Ireland immigrated to the U.S. from Ireland around 1741. Details on children and grandchildren are included when known. The author also includes facts about the times and places where they lived as well as weaving their life stories into local history when he believes it will add value. Details on living persons is limited or intentionally excluded. Extensive references are included as footnotes and an "all name" index lists each person along with page numbers where they are found.

Genealogists and other historical researchers have valued the first two editions of this work, often referred to as the genealogist's bible."" The new edition continues that tradition. Intended as a handbook and a guide to selecting, locating, and using appropriate primary and secondary resources, The Source also functions as an instructional tool for novice genealogists and a refresher course for experienced researchers. More than 30 experts in this field--genealogists, historians, librarians, and archivists--prepared the 20 signed chapters, which are well written, easy to read, and include many helpful hints for getting the most out of whatever information is acquired. Each chapter ends with an extensive bibliography and is further enriched by tables, black-and-white illustrations, and examples of documents. Eight appendixes include the expected contact information for groups and institutions that persons studying genealogy and history need to find. ""
