Family relationships

First-degree family links are those between parents and children. 

Second-degree links include brothers and sisters, and grandchildren and grandparents. 

At the third degree, there are great-grandparents, uncles and aunts, and nieces and nephews. 

At the fourth degree, we find a person’s first cousins.

In short, the degree of kinship represents the number of intermediaries between two people, going back to the common ancestor, then returning to them.
