Definition of family tree

The term "family tree" originates from the visual representation of family relationships. Early genealogists used actual trees to depict lineage, with branches representing descendants. The branches extended upwards, symbolizing the progression of generations. This practice led to the metaphorical use of "tree" to describe a family's ancestry, with roots symbolizing their origin and branches representing their descendants. The phrase became common in the 17th century, solidifying its connection to family genealogy.
