A COUSIN is a relative who shares a common ancestor with another person. Cousins are typically the children of two siblings, or the children of two first cousins. Cousins can also be more distant relatives, such as second cousins or third cousins. In some cultures, cousins are considered close family members and may even be referred to as 'BROTHERS' or 'SISTERS'. The term 'COUSIN' is often used to refer to any relative who is not a direct ancestor or descendant.
