This chart can be used to determine the relationship between two individuals. If you can trace two people back to a common ancestor, you can determine their relationship to the common ancestor, and using the top and left columns find the intersection. That is the relationship between the two people. If you can't trace two people back to a common ancestor, then you are simply out of luck and this chart cannot help.
