Your grandfather's sister's niece (his daughter) is your mother. If your grandfather had more than one sister, your grandfather's sister's niece might not be your mother, but the child of that other sister and would then be your first cousin, once removed. If your grandfather's sister married, her niece could also be unrelated to you. This would be the case if the niece was the child of her husband's brother or sister.
A DNA test performed on materials from you and your aunt (sister of your father) can be done to determine whether the two of you are related. If you are not related, it may mena that your father and his "sister" are not actually related, or it may mean that youyr fatehr is not your biological father.
No, because she is related to you.
Your mother's brother is your uncle. Your uncle's wife's sister is his sister-in-law. There is no family relationship between you and your uncle's sister-in-law's daughter, unless the sister-in-law is married to someone who is related to you.
I believe that would be a fifth cousin
If your sister-in-law is your spouse's sister, her brother is your spouse's brother and therefore is your brother-in-law, or perhaps your husband. If your sister-in-law is the wife of your brother, her brother is your brother's brother-in-law but is not related to you. The English language has no relationship term for the brother of your sibling's spouse.
that would be your grand uncle
The plural of grandpa is grandpas.
