In 1910, the McKinleys were living at 1012 Dearborn, along with two lodgers and a boarder of their own. Mr. McKinley was a railroad engineer. His younger son Harold McKinley, age 17, gives his occupation as “baseball player, professional.” Harold McKinley was out of work for 24 weeks in 1909, however–so maybe he wasn’t quite big-league material just yet. Older brother George McKinley had the altogether more sensible occupation of “steamfitter, shop.”
