Your brother's daughter is your niece. Her daughter is your great niece.
Your brother's son or daughter is your nephew or niece respectively.
Your mother's brother is you uncle and your daughter's great uncle. Your daughter is his great niece.
Your grandfather's brother's daughter is your first cousin, once removed.
If it is your brother's child, she would be your "niece." If the daughter is not fathered by your brother, then she is your "sister in law's daughter"
u got me u are screwed I helped my adopted daughter find her mom and we have learned she has a younger biological brother and sister (different dad). My question is how is my biological daughter related to my adopted daughter's half brother and half sister. Or, is their no relation?
I guess you will be her uncle. Consider this case.. You have a brother and he has a daughter.. Your daughter will be a sister in law to your brother's daughter.
3rd cousin I think:-)
If your daughter's brother-in-law is the brother of your son-in-law he is not otherwise related to you.If your daughter's brother-in-law is husband of her sister, then he is your son-in-law.
