Your grandmother and your wife's grandmother are not related to each other because you are married to your wife.
Especially in small communities, it is possible that they might be related to each other for other reasons. The only way for you to know for sure is to get genetic testing done or do a family tree. Ask other people in the family.
Your grandfather's wife's daughter is either your mother or your aunt.
But if your grandfather's wife's daughter is from a previous marriage, and your grandfather did not adopt her, then she is not related to you, although she would be a step-sister to one of your parents.
If they grew up together, your family might well consider her to be your aunt, and treat her as such.
