Who notably ended a feud with Lachlan McIntosh by dying in a duel?

The correct choice is Button Gwinnett, who is known for his notable involvement in the early political landscape of the American Revolutionary era in Georgia. Gwinnett was a signatory of the Declaration of Independence and also served as the Governor of Georgia. He engaged in a well-documented feud with Lachlan McIntosh, a fellow revolutionary leader, over both political differences and personal grievances. This conflict culminated in a duel in May 1777, in which Gwinnett sustained fatal injuries. His death in this duel effectively put an end to their feud, highlighting the intense personal and political rivalries that were common during this period in American history.

Understanding the historical context of Gwinnett's life and his contributions can provide insight into the challenges faced by leaders during the American Revolution, as well as the cultural norms regarding personal honor and conflict resolution of that time. Other figures mentioned, like James Wright, Lyman Hall, and Henry Ellis, were also significant in Georgia's history but are not associated with this particular duel.
