what is second cousin

A second cousin is a relative who shares at least one great-grandparent with you. To determine the degree of cousinhood, you need to identify the ancestor you share with your cousin and how many generations separate each of you from that ancestor. Second cousins share the same great-grandparents, and you typically share 3.125% of your DNA with them. The term "removed" refers to the number of generations separating the cousins themselves. For example, your first cousin once removed is either your parents first cousin or the child of your first cousin. Second cousins are considered family and not distant relatives.
