Thanks to Louisa co, Va. chancery cases online, I have most of the answers I was seeking. Olivia, Neva were daughters of Robert L Duggins, son of Robert and Rebecca Porter Woodson Duggins. Olivia m. R. Wellford Allen and Neva m. John Latouche. Buena Vista and her sisters, Ada, Anna, Maude Eolia and Lillie Mae were all d. of Thomas Jefferson, called Jefferson, Duggins, another son of Robert and Rebecca. Jefferson's wife is listed as Laura, and I had Lorinda Ann Sims. Maybe Laura and Lorinda are the same. This is Louisa Co. Chancery case # 1910-027. Hope this info helps someone.
