Cousins Chart - A Chart for Calculating Relationships

A Chart for Figuring Relationships
For a true "relationship" to exist, there must be an ancestor who is common to both individuals. If you examine the chart below, the Common Ancestor is Box 0 on the horizontal scale as well as Box 0 on the Vertical Scale. (Based on the system used by courts and most genealogical societies.)

As an example, my mother and my father are both common ancestors for my brother and I. The chart would show us as CHILD in box 1, but SIBLING where those lines meet. Then my children, my parent's grandchildren, show as niece / nephew where that line meets with my sibling, the other child of my parents, and as 1st cousins where their line meets my sibling's child's line... the children of two siblings are 1st cousins. My nephew has no children yet, but my daughters do, so they are his 1st cousins once removed and will be 2nd cousins to his children if he has any.

As you can see from my example, each step a generation away on BOTH sides is a degree of cousinship, but if it only steps a generation on ONE SIDE, that is a removal.
