If your father's will specified that one share was to go to your (now dead) brother or to his heirs, then his widow will get at least part of his share. His children will get some too, according to his will or the inheritance laws of your locality.If your father's will left his estate to his surviving children, and if your brother died before your father, then nothing may go to the widow, etc. However if the brother died after your father, your brother's share is part of his estate.If your father's will specified his heirs by name, then even if your brother died before your father, the widow, and any children, may have a share.You really need to consult an attorney who knows the laws of inheritance in your area and who can review the specific wording of your father's will.
There are three possibilities:If you are male, your sister's sister-in-law could be your wife. Then the sister-in-laws's daughter is yourdaughter.Your sister's sister-in-law could be the wife of your brother. Then the sister-in-law is your sister-in-law, too, and her daughter is also your brother's daughter and thus your niece.Your sister's sister-in-law could be the sister of your sister's husband. Then the sister-in-law is not related to you, and neither is her daughter.
Devoted to her brother and obedient to divine laws is how Antigone feels about her brother and divine laws in "Antigone" by Sophocles (495 B.C.E. - 405 B.C.E.).Specifically, Theban Princess Antigone devotes herself to her family. She particularly is devoted to the most vulnerable members of her family: her disgraced father, King Oedipus, and her disgraced brother, Prince Polyneices. She manifests equally devoted obedience to her gods and her city's cherished traditions.
Officially, I think the term is "no relation." Your father-in-law's father-in-law is, assuming no one's gotten remarried, your wife's mother's father. His sister would be your wife's great-aunt, and her daugher would be your wife's first cousin, once removed.There's not really any concise term for that in English. There may be in some other languages, but I don't know what it would be.If your wife's parents got divorced and her father remarried so that his father-in-law is not your wife's mother's father, then "no relation" is definitely the correct answer.
There is no relation between you and your grandmother's cousin-in-law's grandson.
Your mother's brother is your uncle. Your father is his brother-in-law but he could also have other brothers-in-law. These would be men married to his other sisters, or the brothers of his wife. If they are men who married his other sisters, they are your uncles. If they are brothers of his wife, they are not related to you.
