This chart is based on the system used by courts and most genealogical societies. The numbers at the top and left side represent the generations away from the common ancestor. To identify the relationship between any two people, first identify the common ancestor of the two people. Locate the box in the upper left corner for the common ancestor. Follow the column straight down to find the relationship of one of the two people to the common ancestor. Across the top row of the chart, find the relationship of the second person to the common ancestor.  The highlighted boxes show persons of the same generation. "Removed " indicates that the two persons selected are not of the same generation. This chart may be extended in either direction to identify more distant relationships.
