<P> Among parents, some cultures have assigned equal status to daughters and nieces in their social status . This is for instance the case in Indian communities in the Mauritius, and the Thai Nakhon Phanom Province, where the transfer of cultural knowledge such as weaving was distributed equally among daughters, nieces and nieces - in - law by the Tai So community, and some Garifuna people that would transmit languages to their nieces . In some proselytizing communities the term niece was informally extended to include non-related younger female community members as a form of endearment . Among some tribes in Manus Province of Papua New Guinea, women's roles as sisters, daughters and nieces may have taken precedence over their marital status in social importance . </P> <P> In some cultures and family traditions, it's common to refer to one's first cousin once removed (the child of one's cousin), as a niece or nephew . In archaic terminology, a maternal nephew is called a sister - son, emphasizing the importance as a person's nearest male relative should he have no brothers or sons of his own . Sister - son is used to describe some knights who are nephews to King Arthur and is imitated by J.R.R. Tolkien, especially in lists of Kings of Rohan or dwarves where the sister - son is also heir . Sister - daughter is a less common parallel term for niece . </P> <P> The terms grandniece (great - niece) and grandnephew (great - nephew) correspond to those of granduncle (great - uncle) and grandaunt (great - aunt), expressing a third - degree relationship . </P> <P> For (poorly standardized) terminology such as "second granduncle", see first cousins twice removed . </P>
