What is the child of my second cousin to me?
The children of those second cousins would be third cousins, and they would share one set of great-great-grandparents (again, the same shared grandparents of you and Sue). Your children would still be first cousins and in the same generation, even though one might be graduating from college when the other is a baby.)
What relation is my cousin to my grandchild?
Think of them as first cousins, because they are in the same generation as you, but with an added generation between yourselves and your linking ancestor. Similarly, your child and your cousin’s child are second cousins to each other.
Second cousins share a great-grandparent (3 generations)
What grandparents do 2nd cousins share?
Second cousins share the same great-grandparents. They’re the children of first cousins. And third cousins share the same great-great-grandparents. They’re the children of second cousins.
How are 2nd cousins related?
It means that the closest ancestor that two people have in common is a grandparent. (If they were any more closely related, they would be siblings.) “Second cousins” means that the closest common ancestor is a great-grandparent. Third cousins, then, have a great-great-grandparent as their most recent common ancestor.
Who Are Second Cousins? Second cousins share a great-grandparent, either maternal or paternal. You and your second cousins have the same great-grandparents, but not the same grandparents. If members of your family were adopted, your second cousins may not be blood related to you.

How much DNA do 2nd cousins share?
What is a second cousin example?
Example: The common ancestor is your cousin’s great-grandparent. 1 “great” + 1 = 2, so this is your second cousin. Example: If your great-great grandparent is your cousin’s great-grandparent, then you are 4 generations removed and your cousin is 3 generations removed from your common ancestor.
How are second cousins determined?
Count how many “greats” are in your cousin’s common ancestor’s title and add 1. You now have the correct number label for your cousin. Example: The common ancestor is your cousin’s great-grandparent. 1 “great” + 1 = 2, so this is your second cousin.
What is the relationship of a second cousin?
What is the relationship between my sister’s grandson and my Cousin?
He has three generations between him and the common ancestor (your parents), but your sister’s grandson still has only two generations in-between. So they would be second cousins, but once removed. Likewise, your grandparents’ cousins are your first cousins twice removed because of the two-generation difference from you to your grandparents.
How are you related to your parents’ second cousin?
You and the children of your parent’s second cousin are third cousins, and you share at least one set of great-great-grandparents in common. The same equation can continue for fourth cousins, fifth cousins, and so on.
What is the difference between a second and third cousin?
Your second cousins share a set of great-grandparents with you, your third cousins have the same great-great grandparents, and so forth. So your granddaughter and your sister’s grandson would be second cousins, for example—they have two generations between them and the common ancestor ( your parents).
What does it mean when your first cousin is removed?
“Removed” refers to a difference in generation from you and your first cousin. You can also think of it relative to that shared set of ancestors that you share with your first cousin, which would be your grandparents. “Removed simply means they’re not in the same generation,” Cowan says.
