Third-degree relative

Third-degree relatives constitute a category of family members that largely overlaps with the term extended family, but more limited. Included within this definition are nephews, nieces, aunts, uncles, half-aunts, half-uncles, half-nieces, half-nephews, great grandparents and great grandchildren. The term is most commonly used in reference to the amount of genetic overlap that exists between two sets of people.[1]
