I saw several post that seems to fit these people. 1920 Jefferson County Alabama Census list Emma Yaw age 47 widowed, son Clifton age 25, son Robert age 24, son William age 20, son Lee age 13, daughter Nettie age 10. Living next door to Emma is Walter Yaw (my great-grandfather) with his wife Nerva, daughters Mattie, Bessie, and Birdie. I must assume that Emma is a sister-in-law or some kin to Walter. Please contact me if this information belongs to anyone.
