Hi! You can see John in the 1920 census with his family at: www.familysearchlabs.org Please note in both the 1920 and 1930 censuses he is listed as "Tilson" but it is rendered as "wilson" in the 1920. Dad, Roy, was deceased by the 1930. By 1930 Roy Jr. is married to a lady named Miriam, and they have a child named Marion, age 2. In the 1930 John T. is an auto tool maker. It would appear from the census records that John t. hadat least6 siblings. I did not check any other censuses than the 1920 and the 1930.
