BRANCH. This is a metaphorical expression, which designates, in the genealogy of a numerous family, a portion of that family which has sprang from the same root or stock; these latter expressions, like the first, are also metaphorical.
     2. The whole of a genealogy is often called the genealogical tree; and sometimes it is made to take the form of a tree, which is in the first place divided into as many branches as there are children, afterwards into as many branches as there are grand-children, then of great grandchildren, &c. If, for example, it be desired to have a genealogical tree of Peter's family, Peter will be made the trunk of the tree; if he has had two children, John and James, their names will be written on the first two branches; which will themselves shoot out as many smaller branches as John and James have children; from these other's proceed, till the whole family is represented on the tree; thus the origin, the application, and the use of the word branch in genealogy will be at once perceived.
