Relatives trees are combinations of descendant trees that can be used to show blood relatives or all relatives of the primary person in a single graphic. Descendant trees are not connected using crossing connection lines. Instead, cross-references in the person boxes are used. These cross-references are the same as those used for duplicates in normal descendant trees.

The individual descendant trees are aligned to one another so that the correct generational distance to the primary person is maintained. The cross-references are generally performed within the same generation (row), but duplicates may cause offsets among the generations.

Before the relatives trees are created, they can be configured in the dialog Create Relatives Tree: Individual descendant trees can be excluded from the graphic and the order of descendant trees can be changed. This section does not explain these configuration options in detail.

Relatives trees of blood relatives refer to all descendants of the oldest ancestor of the primary person. For this, the software first determines the oldest ancestors in an ancestor tree structure. It is then determined which of the oldest ancestors is to be used for actually creating descendant trees. If, for example, an oldest ancestor pair is found, only one descendant tree needs to be made. If the oldest descendants have multiple partnerships, the smallest number of descendant trees will be determined to include all blood relatives. The number of generations from the oldest ancestor to the primary person must be specified for all descendant trees so that the correct generational level is determined.

The procedure for a simple example is illustrated with the following pictures (the pictures are valid for the orientation of the tree structure Oldest generation at the top.):

From an ancestor tree structure, the oldest ancestors of the primary person (black box) are determined:

The oldest ancestors (two grandparents pairs) are analyzed to determine which descendant trees are to be created:

For the first descendant tree in this example, the paternal grandmother (red box) has two partners. This means that the first descendant tree will be created for the grandmother and not the grandfather, so that the second partnership of the grandmother and the resulting descendants will be included. The first descendant tree with additional relatives would look like this:

For the second descendant tree in this example, neither grandparent has multiple partnerships. This means that no changes are necessary for the descendant tree. The second descendant tree with additional relatives would look like this:

The descendant trees have been created and assembled to the finished relatives tree:

Notice that the second descendant tree in the relatives tree no longer contains the primary person. As the parents of the primary person (green box and yellow box) are already present in the first descendant tree, the parent boxes in the second tree only contain cross-references to their boxes in the first descendant tree. This method is identical to the method used for duplicates in normal descendant trees.

Relatives trees of all relatives contain all descendant trees of the oldest ancestors of all relatives, not just the oldest ancestors of the primary person. The procedure is similar for creating blood relatives trees, but differs in that ancestor structures for all relatives of the primary person are created for determining the oldest ancestors. It is then determined which of the oldest ancestors is to be used for actually creating descendant trees.

In a relatives tree with all relatives, the identity of the primary person does not affect the included persons, as they are all interrelated. The person used to create the relatives tree with all relatives is not relevant. However, the selection of the primary person does affect the configuration in the Create Relatives Tree dialog: In this list, the descendant trees of blood relatives are listed first, followed by the trees of additional relatives. As the blood relatives may vary depending on the primary person, the contents of this list may vary accordingly.
