William Warren McCullough and wife, Laura Green McCullough are the grandparents of Kenneth Evans, who allowed me to make a copy of his photo. William Warren was born in 1873 in Mississippi. His future wife, Laura Green, was also born in 1873, but she was born in Comanche County, Texas.
The family attended Shiloh Primitive Baptist Church.
For more info, contact the Comanche County Museum and ask that someone look in the Comanche County books, volume 2.
