If your father's brother's niece is really your father's brother's wife's niece, then there is no genealogical relationship.
Otherwise, she's either your sister or your first cousin.
Your fathers brothers are your uncles. You are their nephew, or niece.
Great Niece.
Your neice by marriage
Your brother's daughter is your niece..and you are her AUNT.
Your brothers great granddaughter is your great great niece.
Your sister's daughter is your niece and you are her aunt (if you are a woman) or her uncle (if you are a man).
No because that would be your cousin
Are you asking what you call your brothers daughter? Well if you are your brothers daughter is called your niece.
A paternal niece is a niece on the fathers side. For example:my dad's sisters's daughter is my paternal niece
Your wife's niece is also your niece, and her daughter is your great niece. It is to be hoped that you do not have a relationship WITH her, merely TO her.
It Depends. Not every daughter father relationship is the same. There are daughters who hate their father. And their are some who love them because there he onlyones there for them. Everybody's different.
Your father's brother is your uncle. You are his niece (if you are female) or his nephew (if you are male).
