Searching for information on the daughters of Henry Manning and Lora Dunnigan Manning. Lora and the daughters were listed in the 1910 census of Comanche County, Oklahoma. May have been the town of Chattanooga. Grace L. Manning age 14 and Ruby N. Manning age 12. Have been unable to locate any information on Grace and Ruby since this 1910 listing. I hope someone will be able to help me. Gloria Perkins.
