I found a marriage contract of Etta Luna and Edward on 2 Apr 1888 in Marshall County, Tennessee on ancestry.com/ I am the great-granddaughter of Etta Luna and Julius Edward Nix. They had three children: Myrtle Duanna Nix (my grandmother), born 30 Jul 1889 in Marshall County, Tennessee, Elbert L. Nix born Aug 1895 in Texas, Mary Lucile Nix born 23 Oct 1898 in Dulaney Community, Hunt County, Texas. I am not sure what happened to Etta Luna Nix. My Aunt Bea, Myrtle's daughter, said Etta Luna Nix died. I know that Julius E Nix is in the 1900 Census with new wife Aramenta S, and daughter Myrtle and son, Elbert Nix. Julius and Aramenta haven't been married a year yet in this census. Aramenta had no living children at the time. Just down below in the same census is (Mary)Lucile Nix, she is living with William and Melissa Frazier as an adopted daughter. Her birthdate is listed as Oct 1898. I think Araminta's maiden name was Rambo. Julius Edward Nix and Aramenta Rambo Nix had Elvin L. Nix born 17 Oct 1914 and Horace Nix born 1917 in Texas. I attended Elvin L. Nix' funeral on 12 Feb 1983 in Sweetwater, Texas. I don't know if there was another Etta Luna but Etta had a twin sister named Ella G. Luna who married Rupert (Rufus) Murdock on 07 Mar 1887 in Marshall County, Tennessee. I don't know for sure if Etta married Andy Gregg. It would have had to be soon after the birth of Mary Lucille Nix in 23 Oct 1898. The dates don't match. I hope this helps. Cynthia
