The Boyce–Sneed feud was a conflict in early twentieth-century Texas between two wealthy cattlemen: John Beal Sneed and Albert Boyce, Jr. It began in late 1911, when Lenora (Lena) Snyder Sneed left her husband, John, for a relationship with Boyce. Sneed sought revenge for the sake of his honor and his home, which resulted in the deaths of seven men within the year.
