Among the very early marriages in La Salle county are the marriages of three brothers, William, Joseph, and George Dunavan, with three sisters, Eliza, Nancy, and Katherine, the daughters of John Green, founder of Dayton. William and Eliza were the first to marry, on November 6, 1831. Nancy and Joseph followed on January 26, 1834, and finally, Katherine and George married on June 15, 1837. In later years, Noah Letts, the younger half-brother of the Dunavan boys, reached the age where he was thinking about acquiring a wife. His brother Madison’s wife, who was John Green’s sister-in-law, suggested a Trumbo girl, a niece of hers. Noah, knowing that several Trumbos had also married into the Green family, felt that Dayton was full of his relatives and thought that he would look elsewhere for a wife.
