Your mother's mother is your grandmother.
Your grandmother's brother is your great uncle.
Your great uncle's daughter is your mother's first cousin, and your first cousin, once removed.
Mother's grandson as regards her daughter is either her (daughter's) son or her (daughter's) nephew.
Your daughter's son is your grandson and you are his grandparent.
Your sister's daughter and your son are first cousins to each other.
the son would be the nephew
they both r brothers
You are their aunt or aunt by marriage.
She is your cousin
The relationship to you would be your cousin !
Your brother's daughter is your niece..and you are her AUNT.
Great Niece.
YES
Yes, she did. She had the relationship of a mother that a mother has with her son. As most mothers do.
That would be her great uncle I suppose. Common sense.
First cousins twice removed.
Your younger brother's wife's sister's daughter would be your son's cousin.
Daughter hates mothers should she send mothers day card to daughter
Your brother would be your son's daughter's great uncle and your son's daughter would be your brothers great niece! Hopefully that makes sense :)
