Lonson Seeley, an industrious and successful farmer, was born in Monroe County, New York, in 1844. After serving in the Union army during the Civil War, he returned to Wisconsin where he pursued a career in agriculture. In 1868, he settled in South Dakota and focused on raising hogs and cattle, which proved more profitable than cultivating crops. Known for his diligence and perseverance, Seeley also contributed to the progress of his community, serving on the school board for over two decades. A devoted Republican and esteemed member of the Grand Army of the Republic, he and his family were valued members of the Methodist church.
