Your first cousin, once removed, is the child of your first cousin or is the child of your great uncle or great aunt. (See also REMOVED COUSINS)

If someone is your first cousin, then his or her child is your first cousin once removed. (Once removed means one generation level different from you.) All your regular cousins (first, second, etc.) are at the same generation level as yourself. Those at different levels are "removed." If someone is YOUR first cousin once removed, then you are HIS or HER first cousin once removed also. Your second cousin once removed is the child of your second cousin. Your first cousin twice removed is the child of your first cousin once removed (i.e. the grandchild of your first cousin). Your second cousin twice removed is the child of your second cousin once removed (i.e. the grandchild of your second cousin).

REMOVED COUSINS: If two people are some type of cousins, but they are at different generation levels, then here is the way to compute their relationship.

1. Count how many generation levels they are apart. This is the number they are "removed."
