Thank you very much for this information. According to the 1880 U.S. Census of Lonoke Co., AR, Annie's son Eddie was eight years old (born about 1872). Census information can be way off, so perhaps the Edward you found below is Annie's son. I will do some checking. I believe the William CARTER you found is the correct one. William was married twice, and a son from the second marriage is in the cemetery.
Like you, I had also wondered about Jefferson PRYOR and his children. I wonder if Annie fell through the crack in the census recording.
