The ABCs of Charts and Reports
How do you know which family tree report or chart is right for the purpose you have in mind? What’s the difference between all those options in your genealogy software? And what the heck is an Ahnentafel, anyway? Here’s a quick guide to some of the most popular chart and report formats and terms:
Ahnentafel Numbering: Used in pedigree charts and ancestor-oriented genealogy reports, this numbering system gives unique numbers to the starting person and each ancestor. Double a person’s number to get the father’s number and add one to the father’s number to get the mother’s number. Ahnentafel means ancestor table in German.
All-in-One Tree: This chart in Family Tree Maker shows everyone in your file, including ancestors, descendants and cousins. It’s great for visualizing everyone at once, but quickly becomes confusing as your family file grows larger.
Ancestor Tree: Shows a person’s ancestors. Family Tree Maker provides three forms:
- The standard version is compact and shows the starting individual at the left and the ancestors branching off to the right.
- The fan chart shows the starting individual in the middle of a circle and the ancestors branching out in all directions. You can also select half-circle and quarter-circle variations.
- The vertical ancestor tree shows an individual’s ancestors branching upward.
Cascading Pedigree Charts: Several programs can print a series of numbered pedigree charts showing a person’s ancestry. It’s faster than printing one chart at a time and the chart numbers are calculated automatically.
Descendant Report: Similar to an Outline Descendant Chart (below), the Descendant Report in Generations also includes dates and places of birth, death and burial. It’s useful as a compact format for displaying detailed information on a person’s descendants.
Descendant Tree: Family Tree Maker provides two forms:
- The fan chart shows the first generation as the center circle and each generation of descendants branching outward in a larger circle, half-circle or quarter-circle.
- The standard version is more compact and shows the starting individual at the top and descendants branching off downward.
Family Group Record (or Sheet): Succinctly summarizes your information on a couple and their children. Includes names; dates and places of birth, baptism, marriage, death and burial; and source citations. Arrange these sheets by husband’s last name in a three-ring binder for easy reference at home and on research outings.
Family History Report: Generations’ Family History Report is a book-form descendant report. It’s something like a Register Report (below), but uses a more confusing numbering system. You’re better off using the more standard Register Report.
Fan Chart: Shaped like a circle or semicircle with the starting individual in the middle. A generation of ancestors or descendants appears in each circle moving outward from the center. A fan chart takes up more space than a standard chart, but makes it easy to visualize which branches are missing from the tree.
Genealogy Report: A narrative history showing the ancestors or descendants of the starting person. Ideal for publishing all your information on an individual’s ancestors or descendants in book form. Choose from three numbering systems: Register or NGS Quarterly (Modified Register) for descendants or Ahnentafel for ancestors.
Hourglass Tree: The starting individual appears in the middle with parents and grandchildren above and children and grandchildren below. The best chart for showing one person’s ancestors and descendants.
Kinship Report: Features an alphabetical list of names and each person’s relationship to a selected individual. Lets you quickly see how anyone in your file is related.
Life Bar Chart: These timeline charts in Genelines show important milestones over the course of a person’s lifetime. You can add historical perspective by including national and international events.
Modified Register Report: Identical to the NGS Quarterly Report (below).
NGS Quarterly Report: A narrative report showing an individual’s descendants arranged by generation, this uses an alternative numbering system to the Register report (below). Every child in a family gets both a Roman numeral and an Arabic numeral. A plus sign indicates that a child appears as a parent in the next generation. Both the NGS Quarterly Report and Register Report make good books.
Outline Descendant Tree (or Chart): Shows a person’s descendants in a compact outline format without boxes. Each successive generation is indented a little farther to the right. Since it uses a lot less paper than a comparable tree chart, this works well in a family history book.
Pedigree Chart (or Ancestor Chart): Usually shows between three and five generations in tree form on a letter-size sheet of paper. Like family group records, pedigree charts are useful “at-a-glance” summaries of what you know and they should go in your three-ring binder on research trips. The closest thing to a standard pedigree chart in Family Tree Maker is a “book layout” ancestor tree.
Register Report: A narrative report showing an individual’s descendants arranged by generation. All children in a family get Roman numerals (i, ii, iii …) and every child later listed as a parent also gets an Arabic numeral (2, 3, 4 …) so you can easily trace a family line from generation to generation.
Timeline Chart: This chart in Generations uses bars to show each person’s life span so you can see at a glance who was living in a certain year and whose lifetimes overlapped.
Tiny Tafel Report: For each surname in an individual’s ancestry, the report shows the Soundex code (which groups together similarly spelled names), the range of years when individuals with that name were born and where the earliest and most recent births occurred. This report in Generations is a handy summary of the surnames, time periods and places you’re researching.
Waterfall Chart: In addition to the Top-To-Bottom and Left-To-Right format for descendant charts, Generations’ EasyChart gives this option, with descendants cascading down from upper left to lower right. Choose whichever design you think is the easiest to understand and fits your display area.
