Henry Kingsbury was an early African-American farmer in Yuba City. Born into slavery in Howard County, Missouri, in 1826, he was brought to California as a slave and remained in slavery until the Emancipation Proclamation. During the Civil War, he purchased stock for his master, who was furnishing it to the Federal army. He was married in 1864 to Katherine Calaway, who was also raised a slave in Missouri. They had four sons. We know of Kingsbury because he purchased a biographical sketch in Thompson and West's History of Sutter County, California.
