The only way your sister can be your aunt is if she marries your uncle. That is incest and illegal.
In most cases, your sister's mother is also your mother, and her husband is your father. If you and your baby sister have the same father but different mothers, your sister's mother's father is your father. If you and you sister have the same mother but different fathers, your baby sister's father is your step-father if he is married to your mother.
Her sister, Aga, never married but remained in the home to care for her mother. She had no children.
Your mother's sister's children are your 1st cousins.
If (as a man) you married your sister-in-law's sister then her mother is your mother-in-law. If (as a woman) you married your sister-in-law's brother then her mother is your mother-in-law. If your sister-in-law married your brother then her mother is not your mother-in-law.
she is his aunt and not they cant get married. Since you still share blood with her because you have the same father, your son is related to your sister.
No, her sister Aga never married and remained at home caring for her mother.
Your half-sister's mother may be your mother, if you have different fathers. If you have different mothers and your father is married to your half-sister's mother, then you probably should call her "mother." If your half-sister's mother is not connected to your father (i.e. her father married your mother) then there is no relationship name for you to call her mother, other than "my half-sister's mother."
Yes, a half sister is also a step sister. Wrong. If your mother or father had a child with another person, it'd be your half brother/sister. If your mother or father got married to someone with kids, it'd be your step sister.
Abraham married his half sister Sarah. Gen:20:12: And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.
She would be your aunt. Your mother's brothers are called uncles. If your aunt was married to a male, he would also be your uncle. If your aunt was married to a female, she would be your aunt as well.
Your father's sister is your, paternal aunt,and your mother's sister is your, maternal aunt.Father's sister is your aunt.
Let's break this down:Father's mother's elder sister: your father's aunt, which makes her your great aunt.Your great aunt's son is your father's cousin. Your father's cousin's daughter is your father's niece, which is your 2nd cousin (shared great-grandparents).Father's mother = grandmotherFather's mother's (elder) sister = great-auntFather's mother's (elder) sister's son = 1st cousin once removed (father's 1st cousin)Father's mother's (elder) sister's son's daughter = 2nd cousinIt could be your daughter or niece (brother's daughter) if your great-aunt (your father's aunt) married your father. But it could not be your sister, because it's impossible for your father to be his mother's son and also his aunt's (mother's sister's) son. Unless of course there was some IVF of donated eggs, or that sort of thing.
