Virginia's Northern Neck is comprised of the present-day counties of Lancaster, Northumberland, Richmond, and Westmoreland (the oldest records for Richmond County date from its origin as part of Old Rappahannock County). Mr. Headley has compiled a genealogical dictionary of the earliest settlers of the Northern Neck derived from a database of 74,893 records. Volume Four is part of a six-volume set. In all, the six volumes contain upwards of 24,000 genealogical sketches, arranged alphabetically, and each fact cited includes the source of the information. Each volume contains an Introduction, methodology essay, list of sources, bibliography, list of abbreviations, name variants, place names, and an index.
