I don't know her, as I usually work lines in New England and the Northeast. As with Emma, have you tried https://www.familysearch.org/en ? It's a good place to start. But you will need a reasonable range of dates to find anything helpful.
My family was from Bladen County, North Carolina, Atlanta, Georgia, Sweetwater, Alabama, Horry County South Carolina, and Pittsburgh, PA. My family is black. Our last names are Wright, Cromartie, Nichols, Dumas, and Gordon, and other names. I would need to know what do you want to know. I use the last name Page because that is what my father was using when he married my mother. His actual last name is Wright.
I found this on Geni.com.
