I believe that I may have found your John in the 1930 census as follows:
Vigo Co., Terre Haute, District 33 Mary Abramshead28wid16(age at first marriage), b. ILparents b. IL John F. Abramsson11b. ILparents b. IL Leona Abramsdau9b. ILparents b. IL Elmer Abramsson6b. ILparents b. IL Leon Abramsson4b. ILparents b. IL William Abramsson4(I think-hard to read)b. ILparents b. IL William Caslock/Garlock??(Hard to read) brother27mrd.20(age at marriage)[but where is his wfie?]b. ILparents b. IL
I found these "possible" death records for the father in Vigo Co: Abraham William M W 39 Feb 23 1918 Terre Haute CH-54 144 Abrams James William M W 59 May 2 1919 Terre Haute CH-54 263
You may want to consider getting a death record on him to see if his parent's names are on it.That has helped me a few times.It looks as though you might want to check IL for earlier info. I hope this is of help.
