Give me a second to find my "Sherlock Holmes" cap?(lol) The only certainty is the maiden name of Martha's mom: Givens. The other surnames (Brooks and Coleman) may have resulted from marriages? Start in 1920 Brazos-Precinct 1-District 1-Image 24 and find Martha "Colemon" as the eight-year-old granddaughter of Prince "Givins". Next, 1910 Limestone-Precinct 8-District 49-Image 23 find Prince "Given" with daughter Nancy A. age 21 and widowed. Did she, Nancy, marry Wesley Moses Coleman (26 Apr 1893 - 10 Feb 1965)? I'm clueless! Martha's grandfather found 1930 Brazos-Precinct 1-District 2-Image 16. "Prine" "Givins" lived next to Willie/Martha Steptoe and Robert/Malinda Steptoe. That's it!
