This was an interesting research into this side of my mother's family. It appeared That my great grandmother was listed as Lena on early censuses, but later went by Rhoda. Since she was listed with her big brother, Martin, I followed his paper trail.
So far, the 1920 Census has been one of the most telling about two families and two slaveholders.
Martin Brownlee is listed with his second wife Minnie, but his birth year is off. He is living doors away from his sister's mother-in-law Charlotte Jamieson who is living alongside the Caradines, one of the largest slaveholders in Clay County, Mississippi.

Martin could be her brother. If so, this could be her uncle and grandparents listed in 1880. Lena is the right age to be Rhoda! There is a younger Ned Brownlee (probably son of older Ned), who I thought might be the father of Martin; and maybe Rhoda. But can't find Martin nor Rhoda anywhere in the 1870.
