I am not an Armwood, but have Armwood relatives and have researched the Duplin/Sampson County set. The second wife of my great-great-great-great-grandfather, James Henderson (1818-aft. 1880), was Louisa Armwood, daughter of John Armwood of Sampson Co., NC. Louisa was born about 1830. Their children included Alexander, John Henry, Hepsie, Susan, Nancy, Louella, Edward, and Julia "Molly."
