Per the death cert. which made me think that his mother may have re-married and his step father listed on death cert. as father. Parents were listed as James Milton, and Margaret R Atteberry. Male, white, widowed. Occupation machinist, Frisco Railway. Mrs. Josephine Trible, Springfield, MO. informant. Cancer was the cause of death. Jewell E Windle funeral home. Lived 58 years in the community. Died in Burge Hospital.

I did find a tree on ancestry that listed his father as James Milton Davison, mother Margaret Ruth Atteberry. It did not have marriage info for him though.

Property that Davison is buried on owned by EH and WE Barthelmeyer.

Mother may have went by Ruth her middle name.

Ralph is buried in Hazelwood under the name of Ralph Davison. This census listed him as nephew. Possible error. Although wife maiden name was Belt still the children were sometimes given the maiden name of mother as a middle name. Not sure yet how this will end up.
