Hearing my mother say that she was "going shopping at O'Neil's" is one of those old, old memories of mine from childhood. The big O'NEIL'S sign at the shopping center really left a big impression on me too. I was kind of surprised to see that the changeover occurred much earlier than I thought.
It was a sad thing when the Sheffield Center May Company store finally closed. Many of the employees had been there for years, and had become part of the shopping experience. Also, we went there much more often than the Midway Mall store, as it was much more convenient for us.
Today the former department store complex is the Macy's Systems and Technology center, and the O'Neil's name haunts the area through the street signs.
