That is what is on his death cert. My mother however told me that, that might not be accurate. So your guess is as good as mine. I know that in 1940 they lived at 184 McKintry St in Detroit and that he was already disabled. I don't know if you knew that he was a paraplegic in later life that he died of pneumonia as a result of long term disability. My scanner broke, if you don't have a copy I can get you a copy of his death cert.
