Locate one person along the top row based on their
relationship with the original person. Locate the
other person along the left side column based on their
relationship with the original person. Where the two
lines cross indicates the relationship of the two
people to each other.
If you and I have the same Parents (P), then we are Siblings (S).
Be sure to use the nearest original Ancestor that you
share or you can come up with such ridiculous things as:
Since my Grandparents are my son's Great Grandparents,
therefore my Son is my first cousin once removed
