How does OnePage Genealogy solve the problem with fixed-form pedigree charts beyond 10 generations?
OnePage Genealogy takes advantage of the fact that all family trees have incomplete sub-trees. Few lines are traceable past six or eight generations. The program requires much less paper than a fixed-form genealogy chart would because of its unique utilization of space – it only requires space for names that are found in the GEDCOM file. The tree economizes space by forcing every pair of sub-trees as close to each other as possible. In this example, we see how two separate lines would be laid out in a chart created with OnePage Genealogy. Notice in the second column that John Mack’s parents are unknown. The space that would have displayed his parents would be empty space on a fixed-form chart. This space is used by the ancestor above, Mary Stickney. The algorithm used to achieve the results shown is adaptive to each unique set of records and to each user’s preferences.
