Your mother-in-law's brother and his children are not related to you.
He is your childrens' uncle and his children are first cousins to your children.
You would be 2nd cousins, assuming that the brother's wife's granddaughter is also the brother's granddaughter. If the granddaughter is not the granddaughter of the brother, there is no relationship.
Your daughter's uncle can be your brother. Her parent who is not your sibling (your brother-in-law or sister-in-law) could also have brothers. They will also be your daughter's uncles, but will not be related to you.
It says what relation are your brothers nieces to you.... It could be your child or your niece also causes you can have two brothers and it may be the other ones kids. Or of course it could be your brother's new wife kid by another man making her no relation.
Your sister's mother is also your mother.Your mother's brother is your uncle; and his brother is also your mother's brother, so he is also your uncle.Your uncle's son is your first cousin.
Your brother-in-law is either the husband of your sister or the brother of your spouse.Where your brother-in-law is the husband of your sister, there is no relationship name in the English language to describe his brother's relationship to you. However, in that situation your brother-in-law's brother is your sister'sbrother-in-law.Where your brother-in-law is the brother of your spouse, his brother is also your brother-in-law.
You are your brother's wife's brother-in-law, if you are male. But your brother's wife can also have brothers-in-law who are not related to you or to your brother. They would be the husband's of the wife's sisters.
No, your brother's brother-in-law is not related to you unless you and your brother both married children of the same parents and they had another brother. but the the brother-in-law relationship is not through your brother and his marriage, but because he is the brother of your spouse. Technically, the proper introduction would be, "This is my brother's brother-in-law" as there is no direct relationship between the two of you.
Your sister-in-law's husband is never your brother-in-law. He can be your brother, when your sister-in-law has that relationship to you because she is married to your brother. You could also have a sister-in-law who is the sister of your spouse. But then her husband is not related to you.
He is referred to as your 'Brother-in-law."
If the brother-in-law's daughter is also your sister's daughter, she would be a niece. Otherwise, there is no relationship.
If your wife's son is also your son, then he is your brother's nephew and your brother is his uncle.If your wife's son is a child from a previous, or subsequent marriage and is therefore not your son, he is not related to your brother unless you have adopted him. If you have adopted him, the relationship is the same as if he were your biological child.
