Happy New Year! First, I've peeked at your tree and it is the best of those viewable on ancestry.com. It is not unusual for people to be absent on one census yet enumerated on the follow-up with kids more than ten years old. You have her on your tree married to George P. Parr, 28 Jan 1869. The marriage date courtesy https://familysearch.org/
however she's identified as Iraline G. P. Maddous. Beginning to think all of the siblings had double middle names? Parental confirmation found on death certificate: Bertha Mae Wade (28 Oct 1889 - 19 Sep 1969). If you reside near Rusk County Courthouse perhaps time spent reviewing marriage, birth, and death indexes may expand your knowledge of family? Something to research, marriages for J. H. Bryan(t). Familysearch indicates he wed Jessie Maddoux (6 Mar 1883) then S. E. Maddoux (6 Jan 1886). They may have been sisters, Jessie and Samula? Then, S. P. Johnson wed Mrs. Sam Bryant, 1 Mar 1895. Either the family was well-off financially or John Maddox did not serve during the Civil War? I was unable to pinpoint him to an army unit or find an application for pension as a result. I hope you make a sincere effort to find descendants of Ann E. C. (Maddox) Brown, W. O. W.'s sister? Her great grandson, Matthew Lafayette Vinson III (16 Sep 1943 - 15 Aug 2001) died in San Diego, CA. However, he and Shelia McMahon have two children listed on Texas' Birth Index for Tarrant County.
