A family tree is an excerpt from the descendant table that only includes the bearers of the same family name and their spouses, although strict adherence to this rule is not always possible, for example due to name changes, adoption, foreign naming rights and other things.
Compared to the family tree, the family tree has the advantage of greater clarity, but also quickly becomes unwieldy as the family under consideration grows. Its decisive disadvantage is that it records a state of research in which supplements and extensions hardly need to be incorporated. Even with the use of electronic media, massive formatting problems arise, which can only be solved without great effort by going back to databases and the virtual recalculation of the board each time it is called - which in turn basically means nothing more than saving as a list.
In both forms of representation, the oldest ancestor, the progenitor , the progenitor or the progenitor parents , is attached at the top, in contrast to the family tree , which sees him or her at the root. The other generations follow below in closed rows, horizontally for the family tree, vertically for the family tree. In the family tree, the children of a person are summarized under a bracket.
In reference works , the family name is a sorting criterion and thus the family tree or family list is the natural form of representation, as is the case in family histories. Descendant tables and lists of descendants , on the other hand, predominate in monographs that are dedicated to a specific person and their descendants.
