I see that this post nearly 12 years old so I am not sure if you are watching it anymore or have already found your answer, but I can help you out.
Margret Ann Morris was born September 29, 1869 in Polk County Tennessee and died there on November 10, 1924. She was my great-great-grandmother.
Maggie was the daughter of William Gideon Morris (January 6, 1840 – March 19, 1907) and Nancy Ann Runion (December 18, 1850 – September 24, 1905). William was a confederate veteran of the civil war serving as a sergeant in Company C, 3rd Tennessee Mounted Infantry (CSA).
Maggie had six siblings that I know of. William and Nancy had seven children: Deborah, Margaret Ann (1869, my great-great-grandmother), Elizabeth (1872), John Plesant (1874), William Isaac (1877), Laura Katie (1882), and Robert Lafayette Morris (1887).
Maggies grandparents were, paternal; Shadrick C. Morris (1812-1840) and Mary Ann Hazelwood (1815) and, maternal; Isaac Runion (1819-1877) and Elizabeth Ann Hood (1819-1901).
Maggie married John Winchester Winfred Guinn in 1884 and they had 14 children: Tommy, Willie, Cornelia Ann (1887), Nancy Elizabeth (1889), John Marcus (1891), Abraham Gideon (1893), Lucy Mae (1894, my great-grandmother), Charles Clifford (1898), Essie Mildred (1899), James Blaine (1901), Mamie Kate (1903), Walter Morris (1904), Maggie (1907), and Minnie Jane (1910).
Hope this helps. Email me and I will share all I have. I have traced the Morris family ancestors of Maggie back to Edward Morris who was born in England in 1455. The early Morris family immigrants to America were Welsh Baptists who intermarried with Scotch-Irish Presbyterians.
