What relation is my mother's step-brother?

Answer 1

Your mother's sister's children, sons or daughters, are your first cousins.

The children of first cousins are second cousins to each other. That is the relationship between your children, or either sex, and your first cousin's children, of either sex..

Answer 2

Your grandfather's sister's stepson is not related to you, although you may want to treat him as a cousin if he is well integrated into you family and acting like a cousin (first cousin, once removed).

If your grandfather's sister adopted him, he is not her step-son, but he is your first cousin, once removed.

Answer 3

Your brother's son is your nephew. Your nephew's sister is also the child of your brother and is your niece. The mother of your niece and your nephew is the wife of your brother - and therefore your sister-in-law, unless and until she is divorced from your brother, when she becomes your ex-sister-in-law.
