The Federated Department Stores must have been local to your area. I've known Macy's stores my whole life. As I recall, the 1947 movie, "Miracle on 34th Street" featured Macy's quite prominently.
Federated is, or was, a conglomerate. They acquired Macy's as it was emerging from bankruptcy in 1994, then began rebranding all the other chains they acquired as Macy's stores. Among those stores are Bullocks, Bon Marche, Filenes, Robinsons-May, Famous-Barr, Marshal Field's and Lord & Taylor. Federated changed their name to Macy's Inc. in 2007.
