NGSQ Numbering System

By

Developed by the National Genealogical Society, this genealogical numbering system has a lot in common with the Register System. One major difference is that the NGSQ numbering system assigns numbers to all children in each family, whether or not they have documented descendants. It is the standard for genealogies published in the National Genealogical Society Quarterly (NGSQ), for which it is named, as well as many other genealogical publications.

What is the NGSQ Numbering System?:


Although often mistakenly referred to as the Modified Register System, and sometimes as the Record System, the NGSQ numbering system in use today is actually much more comprehensive and flexible.

How to Read an NGSQ Report:


The NGSQ system, or modified register system, varies from the Register System in that each individual is assigned a number regardless of whether the line is subsequently carried on (whether or not they had children). The individuals who do have descendants are further indicated by the addiion of a plus sign (+) in front of their number.

What Does the NGSQ Numbering System Look Like?:


To look at it visually, here is the layout of a simplified NGSQ report:
