Usage notesEdit

  • People who have common grandparents but different parents are first cousins. People who have common great-grandparents but no common grandparents and different parents are second cousins, and so on.
  • In general, one’s nth cousin is anyone other than oneself, one's siblings or nearer cousins found by going back n+1 generations and then forward n+1 generations. One of my first cousin's parents is one of my parents' siblings. One of my second cousin's grandparents is one of my grandparents' siblings.
  • The child of one’s first cousin is one’s first cousin once removed; the grandchild of one’s first cousin is one’s first cousin twice removed, and so on. For example, if Phil and Marie are first cousins, and Marie has a son Andre, then Phil and Andre are first cousins once removed.
  • In the southern US, the relation is considered the number of links between two people of common ancestry to the common aunt or uncle.
