While searching for Chicago Duffy Florals player Harry Lucas, I noticed he had played some semi-pro ball with a Willis Young. Since Lucas and Young were also teammates for the Florals in the MBC, I think we found that "Willie" is not "William" but "Willis". Looking through Chicago-area newspapers, I find repeated references to Willis who is apparently from Delphi, Indiana (which is near Lafayette). Some poking around genealogical websites and I find a family of Youngs from Delphi in the early 20th centurt with a Willis V. Young who was born in 1909 and died in 1981. All these pieces seem to fit.
