no....because she is a sister for you
Your sister's daughter would be considered your niece.
can it be an incest if a son and a daughter who are related because of their mothers who sisters marry each other?
That would be your cousin so no you can't.
your great aunt.
Your mothers sisters Granddaughter is your second cousin
No. This is a religious relationship, not a family relationship.
Yes, she did. She had the relationship of a mother that a mother has with her son. As most mothers do.
Let's see if we can unravel this. Your sister's husband's father's brother is your sister's husband's uncle. The uncle's daughter is your sister's husband's cousin. There is no relationship to your sister, unless your sister wants to call her a cousin-in-law. To break it down to its simplest terms: She is your brother-in-law's cousin and no relationship to you.
