Oh, good, glad it helps!
Not much is turning up on the two named Elbert and Harry though. Nothing that turned up after the 1930 census for either of them, at least that I could find.
Were you able to find William's parents' names? I did find him in the earlier 1900 and 1910 census living with James T. Johnson born about 1850 in Kentucky and Alice E. Johnson born about 1852 in Illinois.
James' father was born in Maryland and mother in Kentucky. Alice's parents were both born in Illinois according to the 1910 census. Alice was widowed by 1920. She was living with William that year, and as late as 1925 in the Kansas state census, but I couldn't locate her after 1925. In 1930, William was with John and his wife Lily.
