The only areas mentioned in the records are Ashtead, Wervington, and Camberwell, all in Surrey, England.

Author Brenda Dougall Merriman takes readers through the genealogical process of research and identification, while examining how the genealogical community has developed standards of evidence and documentation, what those standards are, and how they can be applied.

The major part of this work is an alphabetically arranged and cross-indexed list of some 20,000 Maryland families with references to the sources and locations of the records in which they appear. In addition, there is a research record guide arranged by county and type of record, and it identifies all genealogical manuscripts, books, and articles known to exist up to 1940, when this book was first published. Included are church and county courthouse records, deeds, marriages, rent rolls, wills, land records, tombstone inscriptions, censuses, directories, and other data sources.
