However, because a parent must be born before their child is born, a person cannot be their own ancestor, and thus there are no loops, so ancestry forms a directed acyclic graph. The Family Tree Relationship Chart works on the principal of finding the common ancestor between any two people. In other words, to determine the relationship between two people in a family tree, it is necessary to know what direct ancestor the two people had in common.
This could be a parent, grandparent, great grandparent, great great grandparent, etc. It has to be the same common ancestor for both people. However, the relationship to the common ancestor does not have to be the same for each person. For example, for one person, the common ancestor could be their grandmother, and for another person the same person could be their great grandmother. Once the common ancestor has been identified, it is a straight forward exercise to determine the relationship between any two relatives.
