If Jane and John are married, and Jane has a sister, Jane's sister is John's sister-in-law. Jane's sister's husband, however, is not related to John, although he is ''Jane's'' brother-in-law.
No
They are brothers-in-law.
Your half-brother...
It depends on which "half" of your half-brother the nephew is related to. Your half-brother shares your father or mother, but not both. If your half-brother's nephew is related to the same parent you are related to, your half-brother's nephew would also be your nephew. If related to the other parent, he would not be related to you.
You dont even have a brother in law :( sorry :'(
If your half-brother has a full sister, she is your half sister. If your half brother has a half sister, she may be your full sister, or she may not be related to you at all.
no he was the brother of agamemnon husband of helen...you are thinkin of the minotaur...
The son of your half-brother's father is not related to you when the father is not your father.
BROTHER AND SISTER. Half brother and sister.
Your half-brother's half-sister could be your full sister, or not related to you at all. For example, say your parents are Joe and Mary and your half-brother's parents are Mary and Steven. Say your half-brother's half-sister is Barbara. If Joe and Mary are Barbara's parents, then she is your full sister and your half-brother's half-sister. If Barbara's parents are Steven and Jane, then Barbara is not related to you (unless there is an adoption).
he is supposed to be his half brother
A half brother means that they either had the same father or mother as the rest of the siblings, but a different father or mother making them a half brother. You Grandmother's half brother would be your great uncle.
Your mother's mother is your grandmother. Her husband is your grandfather or a person unrelated to you who married your grandmother either before or after your mother was born. If her husband is not related to you his son may be your mother's half-brother or may be unrelated. If unrelated the son's son's sister is also unrelated to you. If your mother's half-brother, then the son's son and his sister are your second cousins. If your grandmother's husband is your grandfather, then his son's son (his grandson) and the grandson's sister are both your second cousins.
