A first cousin once removed is the child of a first cousin or the first cousin of one's parent. The term "removed" indicates the number of generations between two individuals in a family tree. For example, a person's first cousin's child would be their first cousin once removed, as they are one generation removed from the first cousin. Similarly, a person's parent's first cousin would also be their first cousin once removed, as they are one generation removed from the parent's first cousin.
It is important to note that the term "first cousin once removed" is often confused with "second cousin," which is a term used to describe a different type of cousin relationship. Second cousins are people who share great-grandparents. The number of the cousin relationship refers to how many generations back the common ancestor is, rather than the number of generations between the cousins.
