I think the hardware store was on State street and I beive he sold tin for roofs primarily. My grandmother used to tell a story that he was burnt out in the Chicago fire and during the fire he loaded his family into a wagon and moved to Waukegan. The family was in Waukegan after that.
I think the photo you have is the same one I have but I will send mine anyway. I'd love to see the photo of RD.
I'm in Des Plaines but we lived in Rogers Park for many years, in fact my mother just sold her house at 7342 N. Bell.
