Your uncle's sister is either your mother or your aunt by blood or by marragie.
Your aunt is your mother's or father's sister, for simplicities sake we'll say a parent's sister. A mother-in-law is the mother of your spouse. In an aunt's case, most likely the mother of her husband.
So your aunt's mother-in-law is the mother of the man your parent's sister married. There is no special word for them and they have no blood relation to you (unless your aunt's husband is your others parent's brother, in which case your aunt's mother-in-law is your grandmother on the other side of your family).
Technically, you're not really related. This is just through marriage; not blood. If your uncle and his wife get divorced then you are not connected to his mother-in-law in any way, shape, or form.
You can think of her as grandaunt but by marriage not by blood.
It is one of two things.
Your brother-in-law's wife could be your sister.
Or your brother-in-law's wife would not be related to you at all.
Thru marrige, my dads sisters husbands sister. Is her nephew a cousin?
in law hence 'in-law'
You are not related to your uncles wife sister. However some may think an aunt
Your aunts and uncles are the sisters and brothers of your parents. So they are "blood related." But you also call the husband of your mother's sister your uncle, and he is not "blood related." So aunts and uncles are not always really related to you.
No if the uncles "not related by blood" has a niece and the niece wants to date the uncles sister's son, it is not incest. Your not related by blood so every thing is ok. If some one is telling you that it is wrong show them scientific fact that you can find on google, just make sure it is a .edu or .gov some .org 's are also okay.
You are not related to all of your brother-in-law's family, but you are related to some of them. You are related to your brother-in-law. You are related to his wife, your sister. If he and your sister have children, you are related to them - they would be your nieces and nephews. But you are not related to your brother-in-law's siblings, cousins, parents, aunts, uncles, grandparents, etc.
Your uncles daughter would be your cousin.
Your uncle is your child's great uncle and your grandchild's great great uncle. Your grandson is your uncles great great nephew.
Your uncle would be your sons great uncle. Normally your Son would also call him 'Uncle .... '
not to be complicated , but if you have an uncle--> he has a nephew--> as you can see that's not complicated . And if you ask what is a uncles NEPHEW related to an uncles grandfather. in what way ....i would say the nephew is is the great gandfathers great grandson.
Your aunt is the sister of either your father or your mother. If your aunt is your father's sister, then your father's cousin is also her cousin. If your aunt is your mother's sister, then she is not related to your father's cousin.
Your brother or sister are your siblings. Your cousins are the children of your aunts and uncles.
Artemis is the daughter of the Titan goddess Leto and Zeus, Olympian king of the gods. She is the twin sister of Apollo; and half sister to Hephaestus, Dionysus, Ares, Hermes; her aunts being Hera, Demeter, Hestia and her mother's sister Asteria; her uncles being Poseidon and Hades.
Since your mother and her sister have thesame aunts and uncles, your mother's sister's aunt is your grand aunt or, as some sat, your great aunt.
