Yes, you are legally and genetically so different that this is legal.
They could be brothers and sisters or the could be cousins
First cousins are relatives who have the same grandparent. Second cousins are relatives who have the same great grandparent Third cousins are relatives who share the same great great grandparent. If you and a relative have great grandparents who were brother and sister, then you share a great great grandparent, and are third cousins.
Two people with the same great uncle may be first cousins or second cousins to each other, or may not be related to each other at all. It depends on whether the great uncle is the brother of a grandparent, or the husband of a sister of a grandparent.
A tenth cousin would be someone who has the same great-great-great-great-great-great-great-great-great-grandparent as you. Someone with the same grandparent as you is a first cousin. If they have different grandparents but share at least one great-grandparent with you, they're a second cousin. And so on. If the number of "great"s needed to reach the same person is different for them than it is for you, you're Nth cousins M times removed, where N is the number of greats on the shorter chain plus 1 and M is the difference in the lengths of the chains. So if my great-great-grandfather (2 greats) and your great-great-great-grandfather (3 greats) is the same person, then you're my third (2+1=3) cousin once (3-2=1) removed.
A person is your second cousin if you have the same great grandparent but not the same grandparent. Another way to think about it is that a person is your second cousin if one of your grandparents was the brother or sister of one of the other person's grandparents.
The relationship between two second cousins is that they are second cousins. That means that one of the parents of one was the first cousin of one of the parents of the other; and that one grandparent of one was the sibling of the grandparent of the other.
In the English language, there is no relationship call "direct cousin."There are "close cousins" and "distant cousins," but the definitions of each are unclear.Then there are more specific terms, such as:first cousin - the child of your parent's siblingssecond cousin - the grandchild of your grandparent's siblingthird cousin - the great grandchild of your great grandparent's siblingfirst cousin once removed - the child of your first cousin or parent of your second cousinand so forth.
Third cousins are people who have the same great-great-grandparent. (Incorrect look below for the revision)AnswerNo offense, but the answer above is incorrect. A third cousin shares the same great grandparent. I have many third cousins whom I am very close with, and they are the children of my mom's first cousin (who are my second cousin).
Second cousin once removed are not at all like fourth cousins. With second cousins once removed, the two people have common ancestor. That ancestor is great grandparent of one and the great great grandparent of the other. Fourth cousins are the great great grandchildren of siblings, so they have a great great great grandparent in common.
Yes. Your kinship is that you are first cousins, twice removed. You are both descended from the same person or couple. That is your great great great grandparent, who is also her grandparent.
Your great grandparent's daughter is either your grandmother or a sister of one of your grandarents. The sister of one of your grandparents is your great aunt. (Some people would say, "grand aunt", which means the same thing.)
Your great aunt's great grandson is your second cousin, once removed.
