What is family tree?
It is simple chart showing family relationships in a tree structure, at it is usual genealogy and medicine but of course can be used for private historical purposes and many other. Family trees are typically represented with the oldest generations at the top and with the newer generations at bottom. There are many different themes of a tree, it can be used to determine all descendants of a single person or it might include all relatives with the same surname which is the same as showing all male descendants in a tree. Cousin is a term that represent relatives with whom one share ancestors, but today it is usually used to describe the relationship e.g. brother, sister, uncle, etc. Cousin chart is somehow similar to family tree, it is used to determine degree of cousin relationship between two or more individuals, but it is not represented as a tree chart, but a simple table.
