Numbering Your Genealogy

Revised in 2008, this edition of Numbering Your Genealogy: Basic Systems, Complex Families, and International Kin clearly defines numbering methods and differences between the National Genealogical Society Quarterly (NGSQ) and Register systems. The content also covers non-traditional families, including adoptions and step-relatives; and describes how to number immigrant ancestors in a family history. A “must have” for every genealogist’s reference book collection.

Numbering Your Genealogy is available in print and as a PDF in the NGS online store.
