For what it’s worth, Wikipedia gives this overview for the fictional movie character’s inspiration:

Indiana Jones is modeled after the strong-jawed heroes of the matinée serials and pulp magazines that George Lucas and Steven Spielberg enjoyed in their childhoods (such as the Republic Pictures serials, and the Doc Savage series). The two friends first discussed the project in Hawaii around the time of the release of the first Star Wars film. Spielberg told Lucas how he wanted to direct a James Bond film - Lucas responded that he “had something better than that”. The character was originally named Indiana Smith, after an Alaskan malamute Lucas owned in the 1970s (”Indiana”); however, Spielberg disliked the name “Smith”, and Lucas casually suggested “Jones” as an alternative.
