But it's not a brand that came out of Chrysler...
Jeep was a creation of Willys, which morphed with the AMC group and were taken over by Chrysler.
Chrysler started in 1924 with a design which Walter P had put forward to Maxwell. I think that's right. Anyway, it was Chrysler and it was innovative with hydraulic -wheel brakes and stuff others didn't have, it sold well and Walter P was happy. He was an industrial and economic genius and knew how to get the right people around him to get the job done, so when he realised he needed a new line to appeal to a lower price buyer he got the boys to work on Plymouth, while he introduced De Soto as a kind of 'test the market' model with new features.
But by coincidence, this was when the financiers behind Dodge approached him to take the Dodge Brothers (and Graham) business out of their hands Chrysler Corp suddenly become much bigger. Imperial was added to the line as a Chrysler model in 1926 but became a separate entity along the way.
Buyouts by Chrysler in later periods added Simca, Rootes Group (Humber, Hillman, Singer, Sunbeam, Talbot) to the names list, but they were never Chrysler-initiated names or brands. Then came AMC with the Jeep.
So it would logically seem that the only Chrysler brand still selling is Chrysler, and it would by no means be selling in the kind of numbers that Dodge or Jeep do. It's really quite sad.
