A Family Group Record, sometimes called a Family Group Sheet, documents a single family unit in detail. While a pedigree chart looks backward at direct ancestors, a family group record looks sideways and downward, focusing on parents and their children.

It records the names, birth, marriage, and death information for both parents, along with details about their children. Looking at siblings and parents together can reveal naming patterns, gaps between births, migrations, remarriages, and other clues that are easy to miss when people are viewed one at a time.

Family group records also work as evidence containers. They give researchers a place to compare conflicting dates, document sources, and keep notes about why one conclusion seems stronger than another. Used together with pedigree charts, they help turn a collection of names into a connected family story.
