Second cousins are people who descend from the same great-grandparents but do not share grandparents. One of each of their parents are first cousins to each other.Know More
The number used to identify types of cousins refers to the number of generations back to the closest common ancestor. An easy way to determine the appropriate ordinal is to count the number of "greats" and "grands" in that person's familial title.
When two cousins are not from the same generation, their relationship is further described with the word "removed." The number of times removed indicates how many generations of difference. So "second cousins, once removed" refers to the relationship between a person and the second cousin of that person's parent, since there is one generation difference between them.Learn more about Genealogy
