Final answer:
The provided references do not include a character named Marge or her relatives. Instead, these historical narratives describe various situations where government forces, including federal marshals, intervened in significant national matters.
Step-by-step explanation:
The student asks about a relative of Marge that required 75 federal marshals to bring down; however, none of the historical incidents provided directly reference a character named Marge or her relatives. Instead, the passages narrate different occasions where federal marshals or other government forces were used to uphold the law, preserve order, or enforce federal mandates. Instances like the integration of the University of Alabama and the crisis involving Governor George Wallace, the Christiana riots involving slaveholder retaliation and subsequent trials, the tax protests led by John Fries against the Adams administration, and the veterans' protest in Washington managed by General Douglas MacArthur are examples of federal authority enforcement.
Unfortunately, with the given context, it is not possible to accurately answer the student's question regarding Marge's relative without additional information. If this is a reference to a historical event or perhaps a figure from a text or show, more specific details are required to provide a precise answer.
