I have two questions concerning family trees:
What is the name of the initial person in a family tree? For example, if you want to know the family tree of a certain person, you have that person in the center and then draw lines from that person referring to all of that person's relatives, ancenstors, descendants, partner and siblings. Is it called individual?
What is the name of the role a certain person has in a family tree? For example a sister, mother, father, aunt, etc?
