Most people have four grandparents, eight great grandparents,16 great great grandparents and 32 great great grandparents.
If one set of your great grandparents were first cousins, then then shared one set of their own grandparents. Then you have 30 instead of 32 great great grandparents.
You would have a variety of different relationships to the cousins of your first cousins. Some of them are you and your siblings, and some of them are also your first cousins. Second cousins of your first cousins may also be your second cousins. In addition, your first cousins will have many cousins who are not related to you at all. You are lreated to your first cousins because each of you have one paret who is a sibling of one parent of the other. But each of you also has one other parent, who also has siblings and the children of those siblings are cousins to one of you but not to both.
Both. The children of your father's siblings are your first cousins as are the children of your mother's siblings.
Anyone who has a great grandparent in common will be second cousins. Another way to look at this is to note that the grandchildren of your great aunts and great uncles are your second cousins. Their children are your second cousins, once removed, and their parents are your first cousins once removed.
The two great grandmothers are first cousins to each other and therefore share a grandparent. That common ancestor is the great-great-great-grandparent of both Jack and Jill. * First cousins share a grandparent. * Second cousins share a great-grandparent. * Third cousins share a great-great-grandparent. * Fourth cousins share a grea-great-great-grandparent. Jack and Jill are fourth cousins to each other
Since your great grandfather was brother to the other person's great grandfather, the two great grandfathers had at least one parent in common. That parent is your common ancestor, the great great grandparent of both of you. People who share a grandparent are first cousins. People who share a great grandparent are second cousins. People who share a great great grandparent are third cousins. You are third cousins.
AnswerNo. They are not related--if this is what you mean...If your father has a nephew, and your mother has a niece...you are related to BOTH of them (1st cousins). However, they are not related to each other (unless, of course, your parents themselves are cousins...etc.)
Your child and your first cousin's child are second cousins becase they share the same common ancester(s) and that is your Grandparents, your child's Great Grandparents. You and your cousin's child are first cousins once removed becasue the both of you are in different generations and have no ancesters in common and the 'once removed' means that they came one generation after you.
Cousins are the children of of both your parent's siblings (your aunts or uncles.)
The problem with this question is that you are either first cousins or second cousins. You can't be both first cousins and second cousins - unless there's been some inbreeding already - since one of those terms necessarily defines your relationship. Your first cousin, or called simply cousin, is the child of your mother's or father's sibling. First cousins share two grandparents. Your second cousin is the child of your mother's or father's cousin, one generation lower than a first cousin. Second cousins share two great-grandparents. You've probably also heard the term "removed". The number of times removed is the number of generations apart you are from the person. For instance, my grandmother's first cousin is my first cousin twice removed, since we are two generations removed from one another. My mother and her daughter would be second cousins, and her grand-daughter would be my third cousin. So, as potential spouses, you can only have one relationship to each other, and once you figure out what your relationship to one another is, that's when you'll be able to determine the legality of the marriage.
Double first cousins arise when two siblings reproduce with another set of siblings and the resulting children are related to each other through both parents' families. Double first cousins share both sets of grandparents in common and have double the degree of consanguinity than ordinary first cousins. Double second cousins would be the children of double first cousins. Two cousins are removed when they are are a different number of generations from their shared ancestor. When that difference is one generation, they are once removed. For example, if Joe and Ethyl are first cousins and Ethyl has a son named Bob, then Joe and Bob are first cousins once removed. (But Bob and any of Joe's children are second cousins.) If Bob has a daughter named Mary, Joe and Mary are first cousins, twice removed, because they are two generations separated from each other.
Orion Black is Sirius and Regulus Black's father. They are both first cousins of Bellatrix Lestrange.
Bipolar isn't a direct consequence of being the child of first cousins. If nobody in the family has had it, it is highly unlikely that you will. However, if there is a tendency to bipolar in the family, having that from both parents does increase the risk.
