My latest theory: Grace e Buck's Parents were Wiliam Buck and Victoria Spragens.
William Buck born Fentress, Tennessee 2 Nov. 1851 Marries Victoria 11 Feb 1875 they have the following children Joel wtb 1877 Hancock county, KY Died 1878, Florence 1878 Casey County, KY, Julius Va 1883-1886, hancock County KY, William E. June 7, 1888 Hancock County, KY William Buck (the father) Dies 12 Nov 1887 Hancock County, KY, Victoria marries Otha M. Skinner 1887 1900 Census living in Pellville, KY 1907 lived in Owensboro, KY. On 1900 Census Noah Hardin and Grace E. Buck who are married live next to Otha and Victoria Skinner. in Pellville, Hancock county, KY Grace Hardin sometime between 1922 and 1930 divorces Noah and Marries Chester K Southern and they show up 1930 Census Huntington b.each, CA Grace Dies Dec 31, 1936 kern county CA burred in Bakersfield. Obituary for grace shows her Sister is Florence and her brother WE Buck. I forgot to mention Victoria born in KY and Grace in Census record shows her parents born Father Tennesee Mother Kentucky.
