Your uncle's nephew could be:
not to be complicated , but if you have an uncle--> he has a nephew--> as you can see that's not complicated . And if you ask what is a uncles NEPHEW related to an uncles grandfather. in what way ....i would say the nephew is is the great gandfathers great grandson.
Your uncle's nephew may be either a sibling or a cousin or yourself.
Your uncle is your child's great uncle and your grandchild's great great uncle. Your grandson is your uncles great great nephew.
It could be your son. It could be your nephew as well. It could be no relationship to you at all. The question is do you share a common ancestor? If you do not have a common ancestor, you are not related.
The English language does not contain a specific term to describe a relationship between you and your nephew's wife. The culture does not consider her to be related to you. Most aunts and uncles would merely call her "my nephew's wife."
Your father's brother is your uncle. You are his niece (if you are female) or his nephew (if you are male).
Your fathers brothers are your uncles. You are their nephew, or niece.
Disowning YOUR uncles is not something that an unrelated person can do. Also while you, as their nephew or niece, can simply decide never to see or communicate with them again, there is no legal means of disowning them, they will still be YOUR uncles.
Your uncles daughter would be your cousin.
I believe they would be great aunts or great uncles.
You are not related to your uncles wife sister. However some may think an aunt
No if the uncles "not related by blood" has a niece and the niece wants to date the uncles sister's son, it is not incest. Your not related by blood so every thing is ok. If some one is telling you that it is wrong show them scientific fact that you can find on google, just make sure it is a .edu or .gov some .org 's are also okay.
