Splitting up Large Trees

Note 1: The following procedures are only supported for ancestor trees and descendant trees but not for descendant trees of grandparents, descendant trees of great-grandparents and relatives trees.

You may want to divide very large trees into several partial trees for a number of reasons. For example, a complete tree with a width of 800 inch is not feasible, or the available paper formats for the intended bound family chronicle are limited to Letter format or smaller. In this case, the graphic needs to be distributed across several pages without losing the overview of the complete structure. FamilyTreeFactory offers various functions for this purpose.

The solutions vary significantly, depending on whether the complete tree you wish to divide contains duplicate pairs which are separated into different partial trees as a result of the division. In this case, the cross-references in the duplicate person boxes should direct the user to the corresponding person boxes on other pages. The cross-reference is realized with the use of ancestor or descendant numbers which are specified for the complete tree you wish to divide. They are unique for all partial trees across all the pages.

In FamilyTreeFactory, partial trees connected by unique ancestor or descendant numbers and/or duplicate cross-references are referred to as connected partial trees, while the others are called simple partial trees.

The corresponding creation is illustrated in the sections Simple Partial Trees and Connected Partial Trees.

The optimization of partial trees is explained in the section Optimization of Partial Trees.

Note 2: With respect to partial trees of complete descendant trees, it is possible that unknown parents who are only displayed based on the existence of a child do not appear in the last row of a partial tree because no child is associated with them. However, both the child and the unknown parent will be displayed in the partial tree underneath.
