Ummm... I think so because the sister's cousin has to be related to you unless she is a stepsister.
Your sister's cousin is your cousin, too, unless you and your sister are really step siblings with different parents. Then your sister's cousin is not related to you.
your half sisters cousin would be your cousin
no, unless you are saying your cousins sister, but if your not then no.
Your aunt is the sister of either your mother or your father. Your aunt's sister is either:your mother, and her daughter is you (if you are a girl) or one of your sisters, oranother one of your mother's sisters, and her daughter is your first cousin, or,one of your father's sisters and her daughter is your first cousin.
The relation of the mother;s sister to daughter is niece-aunts.
yes they are cousins not sisters.
Your grandmother's sisters daughter is your parent's first cousin, and your first cousin, once removed.
Lets say you only have ONE first cousin... Your mom and your cousin's mom are sisters. Your father and your cousin's father are brothers. Doubling the genes you have in common... or your mom and your cousin's dad are brother and sister... and your dad and your cousin's mom are brother and sister...
Your mom's elder sister is your aunt; the son of your aunt is your cousin, and the daughter of your cousin is your cousin once removed.
Your father's sister is your aunt and her son is your first cousin.
no just as long as their is no dodgy age difference.
Your father's sister is your aunt. Her son is your first cousin. Her grandson is your first cousin, once removed.
