Well I did cite the wrong year of 1940; I did this absentmindedly because I was looking at the 1940 census at the time. However, what I was actually referring to was columns 17, 18, and 19 of the 1940 census. These columns indicate that James Harlam was living in Long Beach, CA in 1935. That's why I think he may have gone back there after his marriage to Truella disintegrated, and why John may have followed him there after John's mother and stepfather died.
Thanks for your replies.
