A family tree is a chart representing family relationships in a conventional tree structure. The more detailed family trees used in medicine, genealogy, and social work are known as genograms.
Family tree representations[]
Genealogical data can be represented in several formats, for example as a pedigree or ancestor chart. Family trees are often presented with the oldest generations at the top and the newer generations at the bottom. An ancestry chart, which is a tree showing the ancestors of an individual, will more closely resemble a tree in shape, being wider at the top than the bottom. In some ancestry charts, an individual appears on the left and his or her ancestors appear to the right. A descendancy chart, which depicts all the descendants of an individual will be narrowest at the top.
The Family Tree of Sigmund Christoph von Waldburg-Zeil-Trauchburg
Family trees can have many themes. One might encompass all direct descendants of a single figure, or all known ancestors of a living person. Another might include all members of a particular surname (e.g. male-line descendants). Yet another approach is to construct a tree including all holders of a certain office, such as kings of Germany. This relies on dynastic marriage to hold together the links between dynasties.
A very old and extensive tree is that of the Lurie lineage — which includes Sigmund Freud, Martin Buber, Rashi, Hezekiah — and traces at least back to King David born c.1037 BC [1][2].
