Where did Jeep get its name?

Except for the theories on this website halfway down, are they are more sound origins?

Cecil speaks:

Eugene the Jeep

Jeep! Jeep!

A more detailed history of the Jeep

The CJ2A Page used to be my website. I’ve been overwhelmed by other things (as you may know from some of my posts over the past eight or ten months) so I turned it over to someone else. Anyway, there’s a lot of good information about the CJ2A jeep and links to other Jeep sites.
