Linda: Do you know if the Richard Fowler in AR is Richard William Fowler, III? Do you know his DOB? He would be 65 this year if born in 1944. I found a phone no. and address in AR and will try to reach him. Do you know what children the Nobles had? If one of their children was Francis Louise it is possible the grandparents did raise R W Fowler, III.
My father was in the Army at the time R W Fowler, III was born. The birth certificate also says that this mother had another living child in 1944. You can check the 1930 census data for the Noble family and see what shows up.
