Relationship Chart
- For a true "relationship" to exist, there must be an ancestor who is common to both individuals. If you examine the chart below, for example, the Common Ancestor is Box 1 on the horizontal scale (HS) as well as Box 1 on the Vertical Scale (VS).
- Let us suppose that you have a grandson of that common ancestor, as seen in Box 3 of the HS, and you want to know that grandson's relationship to a great-granddaughter, who would be seen in Box 4on the VS.
- If you follow Box 4 (VS) down to where it meets the horizontal pathway to Box 3 on the HS, then where those paths cross, it tells you the relationship -- they are first cousins once removed.
