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.
No you shouldn't date your sisters cousin because its wrong and he or she is related by blood.
Ummm... I think so because the sister's cousin has to be related to you unless she is a stepsister.
It's your cousin.
Your nephew's first cousin may or may not be related to you, depending on how the cousin is related to your nephew. Your nephew's cousin may be your child, or the child of one of your brothers or sisters. Your nephew is related to you by being the son of your sibling. That sibling has a spouse who may also have borthers and sisters. The children of any of those brothers and sisters are also your nephew's first cousins, but are not related to you.
Your are related to some of your first cousin's aunts and not to others. The aunts of your first cousin to whom you may be related are your mother and her sisters or your father's sisters. One of the parents of your first cousin isn't related to you, but married into the family. Anyone of your cousins aunts who are related to that person would not be related to you.
Your mothers sisters Granddaughter is your second cousin
There is probably no relationship at all. You must share a common ancestor to be related. A cousin's cousin is not likely to share anyone, but it is certainly possible.
The relationship stops with your parents. Neither you or your brothers and sisters are related to the cousin. (But you can be friends).
Your grandmother's sisters daughter is your parent's first cousin, and your first cousin, once removed.
No. Neither is your cousin-in-law, or her sisters. In-laws are not blood relative (i.e., members of your family or lineage) therefore anyone related to an in-law is not a relative.
Your first cousin's niece is the daughter of her brother or sister. Your first cousin's brothers and sisters are also your first cousins. So your first cousin's niece is the daughter of your first cousin and is therefore your first cousin, once removed.
Your 2nd cousin
