No, they are not brothers. Bowser is Junior's father and Jacques Pierre Francois is Jeffy's father. Nancy is Jeffy's mother, and Junior's mom is unknown (has been people like Peach and Sheila before). Even though Jeffy was adopted, that still does not make him his brother. Two rights can lead to a wrong people.
