Consanguinity: Kinship Chart
How are you related to another in your extended
family?
Person A Person B
If both A and B have the SAME grandparents, they are first cousins.
The children of A and B are A and B's first cousins, once removed.
The grandchildren of A and B are A and B's first cousins, twice removed.
Since the children of A and B have the SAME great-grandparents, these children
are second cousins.
Since the grandchildren of A and B have the SAME g-g grandparents, these
grandchildren are third cousins.
If both A and B have the SAME g-g-g-grandparents, they are fourth cousins.
