Uncle: the brother of your mother or father; the husband of your aunt
aunt: the sister of your father or mother; the wife of your uncle
brother: a boy or man who has the same mother and father as another person

Say I have a sister and my son calls her "aunt", for example, "Aunt Mary"
I have many cousins, too. They are children of my father's brothers or sisters.
What does my son call my cousins? "Uncle Tom" etc?
I am confused.
