You kids seriously need to do some research first.
Abercrombie & Fitch owns four concepts: A&F, abercrombie (kids division), Hollister Co., and Ruehl.
Limited Brands owns 8 concepts: The Limited, Express, Victoria Secret, Eponymous Limited, Bath and Body Works, White Barn Candle Co, Avra Science, and Heri Bendel.
Limited Brands also used to own these companies:
Limited Too, spun off in 1999
A&F, spun off in 1998
Lane Bryant, spun off in 2002
American Eagle Outfitters owns no other concepts and no one owns them. As far as I know, they are a privately held Pittsburg company.
Aeropostale is owned by Bear Stearns Merchant Banking, and also owns the brand JimmyZ.
