Arbor consanguinitatis

ARBOR CONSANGUINITATIS. A table, formed in the shape of a tree, in order to show the genealogy of a family. The progenitor is placed beneath, as if for the root or stem the persons descended from him are represented by the branches, one for each descendant. For example : if it be desired to form the genealogical tree of Peter's family, Peter will be made the trunk of the tree; if he has two sons, John and James, their names will be written on the first two branches, which will themselves shoot as many twigs as John and James have children; these will produce others, till the whole family shall be represented on the tree.
