I found a transcription that says "Sopretha Wilson" and another that says "Sepeeta Wilson."
I also found a user created tree on that shows a Walter Benjamin Melton (1875–1940) of Darlington, South Carolina marrying a Bertha Holloway (born 1876) around 1894 and having a daughter named Ola around 1900.
I also noticed the death certificate seems to list the father to be "W. D. Melton" but Lola's profile lists him as "William Benjamin."
No answers...but maybe some helpful leads.
