Can I marry the son of my grandfather's sister?
The son of your grandfather's sister is your mother's cousin.
You should call uncle. This is incest. Will be morally condemned.
In addition, you and your grandfather are two generations of immediate family members, and your grandfather's sister's son is a generation of collateral relatives.
Legally speaking, it is possible.
