Looking for Smith & Mathers 1900's or earlier

y Grandmothers name was Gabriel Lola Smith born in 1905 Miami Florida. She lived in Homestead Fl via census report from 1910 naming her mother as Minnie M. Smith(maiden Mathers) and father Isaac L. Smith. On the census it says that Minnie was 27 yrs old and Isaac was 41. Census report also states that both there parents were from Florida. Early on in the marriage they divorced. My Grandmother Gabriel had said that she lived on a Indian reservation at some point. So I don't know if this means she's Indian or any other information on her parents. Any information would be much appreciated.
