Yep, the Cherokee is the small station wagon rig, usually 4 door, but some 2 doors were also made, as well as a pick-up version. The Grand Cherokee is the more modern, fancy version ( still a very capable off-roader ).
Check with various Jeep web sites, some versions of the Cherokee are more trouble free then others, ditto how they are equiped ( for instance, some used a French-made stick shift, which isn't particularyl well thought of.
