The Pedigree Resource File is of no help...
"United States Census, 1880," database with images, FamilySearch (https://familysearch.org/ark:/61903/1:1:MFJN-RVM : 14 July 2016), Sarah Everett in household of M L Everett, Precinct 5, Van Zandt, Texas, United States; citing enumeration district ED 123, sheet 122C, NARA microfilm publication T9 (Washington D.C.: National Archives and Records Administration, n.d.), roll 1330; FHL microfilm 1,255,330.
The 1880 Census puts her in Texas as single. And age 3...
Mom and Dad are in Texas in the 1900 Census living with their oldest daughter, but Sarah is nowhere to be found.
So she either married, died, was missed on the census or just plain disappeared for some reason. I'm thinking married or died is the most likely, but little evidence of it. That first marriage document is a bit vague, the dates line up, but why would she go back to Mississippi from Texas when it appears her family stayed there?
