A Lords wife is called a Lady.

You would call your wife's sister your sister-in-law. If your wife would have a brother he would be your brother-in-law. It is the same thing for a husband's siblings. Your wife's mother would be your mother-in-law. Her father would be father-in-law.
We call "Mami" to moms brother's wife.
Your brother's wife would be called your sister-in-law.
You would call her your stepmother.
Your wife's brother would be called "brother-in-law".
The English language has no special name for a nephew's wife and does not consider you to be related to you. You would simply call her "my nephew's wife."
Unless you are in a polygamous marriage, you are your husband's wife, so you would call her your mother.
Your wife's brother would be called "brother-in-law".
The same way you would refer to anyone else's wife: Mrs. [last name]. For example, if you are referring to the wife of Reverend Brown, you would call her "Mrs. Brown."
Your Grand-daughter-in-law. Hope that helps :D
