I have always wondered about the multiple Giants but never looked it up. Apparently they are related, but only because they were acquired by the same company. They just seem to be grocery chains in neighboring markets that had the same name. I also looked up Giant Eagle. It's also seemingly unrelated, and started as Eagle but then added on "Giant" after an acquisition of a large chain (that was named OK, not Giant).
