Jul 23, Quick Tip: Your parent’s first, second, and third cousins are also your first, second, and third cousins- but once removed. This is because your parents and their generation are 1 above yours. Likewise, your grandparents’ first, second, and third cousins are also your first, second, and third cousins, this time twice removed. This pattern continues throughout each generation.
The second cousin connection is actually quite simple: the common ancestor is a great grandparent, so, in the family tree to the left, Betty Driscoll and the John Doyle born in are second cousins because they share the same great grandparents.
The first cousin once removed relationship is slightly more complicated: it means that the common ancestor is a grandparent to one person and a great. First cousins, second cousins, and so on belong to the same generation as one another, counting back the same number of generations to their shared ancestors.

This one-generation difference equals"once removed." Twice removed means that there is a two-generation difference. You are two generations younger than a first cousin of your grandmother, so you and your grandmother's first cousin are first cousins, twice removed.
