If a man has a daughter from a revious marraige, that daughter is the step-daughter of the second wife, and the second wife is the step-mother of the daughter.
3rd cousin I think:-)
Mother's grandson as regards her daughter is either her (daughter's) son or her (daughter's) nephew.
Your step sister's husband is your step brother-in-law.
There is no relation that is properly called a step cousin.
Your sisters daygter is your neice!
your step son in law it like the same thing as a son in law except its your step daughter's husband.
Your husband's step-daughter could be your daughter.Your husband could also have a step-daughter who is the daughter of a previous wife from her prior marriage to someone else. In that case, his step-daughter is not related to you, unless you adopt her.
Your daughter and your sister's child are first cousins. Your daughter and your sister's grandchild are first cousins, once removed.
She would be his step sister.
Your sister is great aunt to your daughter's child. The child is your sisters great nephew (if a boy) or great niece (if a girl).
The relation of the mother;s sister to daughter is niece-aunts.
Miranda is the daughter of Geoff and Susan Tate. She is Geoff's step daughter in which Susan had from a previous relationship.
your step niece,,, if it was your brothers own daughter it would be your niece, since its his stepdaughter, than its your step niece.
Yes she has a daughter named Grace Penner!
Not sure but i guess it would be your great aunt's daughter
In most cases, your stepfather's wife is your mother. If your stepfather is no longer married to your mother, and has married someone else, then that person is not related to you (unless you count "step-stepmother") and, assuming the marriage ended in divorce, he is now your ex-stepfather. However, if your stepfather is your legal guardian, or has adopted you, it may be convenient to consider his wife to be your stepmother.
