Support for Becky Grey's Unmarked Grave

On June 18, 1956, my grandmother, Becky Grey, and great-grandmother, Lillie Barnes, were murdered by my grandfather. My mom and aunt witnessed everything. For years, I have been trying to find where they both are buried. I located my grandmother's grave today at Westview Cemetery in Atlanta. She does not have a headstone or any markings on her grave. Adding one is $1500. Please help me honor her life so she is not forgotten.
