Family Tree Terms & Meanings
Family Trees are schematic diagrams representing lineage. While they help to illustrate your genealogy, they are not complete. Much as an electrical diagram illustrates a machine, it does not describe the machine. Programs such as Ancestry create a by-product of a family tree while helping you identify and build your family data, including photographs, records, and other documents. This is your genealogy.
People can see and understand a family tree diagram. It has become the manner in which we show our blood and marriage relationships and we can see where we fit. Some of the terms used in genealogy are helpful to understand those relationships, so a glossary is helpful.
term – definition
assumption of the role of parenting, usually legal adoption whereby all rights and responsibilities transfer to the adoptive parents and the child is legally considered a child of the adoptive parents
kinship term meaning by marriage. On any family tree, an affinal relationship is signified by the term in-law

ascendant family tree
the pedigree family tree is sometimes called a direct lineage or ascendant family tree. The pedigree family tree begins with you (or a parent, or grandparent) and then follows a single bloodline or family name back through the generations as far back as you can go.
the outward division or multiplication of paths (child or children) originating at a source – that source being parents
circle (of time)
a shape consisting of all points in a plane that are a given distance from a given point, in our case it is circles of time in decades outwardly radiating from great grandparents
person to whom two people are descendant
confluence (of current time)
occurs where two flowing times join together to form a single channel – in our case it is time flowing from the beginning of two separate generations (your grandparents). Using maternal and paternal trees, each radiating time, they intersect at common decades or the “confluence of current time” (c) copyright
having the same ancestry or descent; related by blood. It is the property of being from the same kinship as another person. In that aspect, consanguinity is the quality of being descended from the same ancestor as another person

family tree = genealogical tree
which is a genealogical chart showing the ancestry, descent, and relationship of all members of a family or other genealogical group, a diagram showing the relationships between people in several generations of a family. A family tree, put simply, is a record of a family’s lineage. On the surface, family trees are interesting bits of recorded history that help us know where we came from and possibly give some clues as to where we might be headed. Family trees can take on more importance as things change. The more detailed family trees used in medicine and social work are known as genograms.
