Names, birth dates, marriage dates, and photographs can all be included in a family tree. Family trees can be basic and only contain close relatives, or they can go back many generations to show you where you originated from, who your ancestors were, and how you are linked to them.
A family tree may also be used to illustrate direct descendants of a notable historical figure, as well as all family members with the same surname.
Furthermore, a family tree might indicate generations of office holders who are not necessarily related, such as Kings and Queens.
