14th June 2019Genealogical data can be represented in several formats, for example as a pedigree or ancestry 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.
