Screven and Arnold Families of Savannah, GA
The Arnolds had nine children. Seven lived to adulthood, including Thomas Clay Arnold, who married Elizabeth Woodbridge Screven in 1870. Prior to this marriage, the Arnold and Screven families had mutual business interests in the Savannah, Albany & Gulf Railway (later the Atlantic & Gulf Railway), a segment of which was constructed through Arnold land. For a more complete biography of Richard James Arnold, see Charles Hoffman, North by South: The Two Lives of Richard James Arnold (Athens: University of Georgia Press, 1988).
Three generations of the Screven family were civic leaders of Savannah, Georgia, and rice planters in the marshy lands surrounding the city: Major John Screven, his son James Proctor Screven, and his grandson John Screven. Although each generation was nurtured by productive and feisty women, three men in particular emerge as focal points of the family's history. John Screven (d. 1830) was the son of Elizabeth Pendarvis Bryan (widow of Josiah Bryan) and John Screven. He married Hannah Proctor and they had three children who lived to adulthood, including a son, James Proctor Screven (1799-1859). When Hannah died, John married her sister Sarah Proctor; most of their children did not survive infancy. Sarah and her widowed sister Martha Proctor Richardson together ran the Screven household in Savannah.
James Proctor Screven attended Jefferson Medical College in Philadelphia, Pennsylvania, graduating in 1820. He continued his studies for several months in Europe, but had returned permanently to Savannah by 1823. His marriage to his cousin Hannah Georgia Bryan in 1826 reunited the Screven and Bryan clans. During the early years of their marriage, James Proctor and Georgia lived in Savannah, where he entered into a medical partnership with Dr. William C. Daniell in 1828. Early in the 1830s James Proctor gave up his medical practice and moved his wife and their two children, John (b. 1827) and Ada (b. 1831) to the Bryan estate, Nonchalance, on Wilmington Island near Savannah. There the Screvens grew rice, had two more children, Thomas Forman (b. 1834) and George Proctor (b. 1839), and began to enlarge the family's landholdings. In the 1840s James Proctor bought Ceylon and Brewton Hill plantations on the Georgia mainland, and by 1859 the Screven family also owned Union Ferry and Proctor's plantations as well as land on Tybee Island. In 1849, Screven's interests took yet another turn when he was elected an alderman of Savannah and the family returned to the city. In this same year, John Screven married Mary White Footman.
