I located the transcribed version of the marriage certificate mentioned above, (in Lamar County, Texas):
"Texas, County Marriage Index, 1837-1977," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:FX9T-WJ5
: 21 July 2017), Walter J Burris and Levie Stewart, 02 Jan 1907; citing , Lamar, Texas, United States, county courthouses, Texas; FHL microfilm 1,293,682.
Name: Walter J Burris; Event: Marriage; Event Date: 02 Jan 1907; Event Place: ___ Lamar, Texas, United States; Spouse's Name: Levie Stewart
Also found a marriage record for a daughter of W. J. Burris and Levie Stewart at https://www.familysearch.org/ark:/61903/3:1:3QSQ-G93H-4GQJ?i=1814&cc=1804002
It was Lola Margaret Burris's second marriage, occurring in Las Angeles County, California. The daughter's name at the time of the marriage was Lola Margaret Parker, so she must have married someone named Parker first. She was born in Paris, Lamar County, Texas (meaning the daughter was).and was 22 years old when this marriage took place -- in April 1931.
Lola's mother's name is spelled "Mrs. Leve Stewart" on the document, and her place of birth is listed as "Tesas" (probably a typo).
Not an answer, but perhaps there are some clues here. I'm trying to think of what "Levie" might have been a nickname for (if it was a nickname). Maybe "Olive" or "Olivia"?
(I didn't totally understand how you came to have Stewart names from previous generations that you believe are linked to Levie. Perhaps if you could provide a bit more explanation about how you came to believe they might be connected, it would be easier to figure out where she came from.
