Located in Carrollton, Illinois, the Greene County Historical and Genealogical Society's mission is to research, collect, care for, exhibit, and interpret items that illustrate the history of Greene County from settlement to the present time, and place them in the context of the history of the State of Illinois. Located in the Lee-Baker-Hodges House, the organization disseminates historical information by publicizing such material in newspapers or otherwise, by developing educational programs, and by operating a museum for the benefit of the public.

No specifics about the museum's operations or contents offered.

Looks like there may be some small museum-type displays in the Society's office, but is it actually a museum proper?

The Society operates the Hammel Museum, housed in an 1800s structure which started as a beer garden and, in the intervening century, became successively a brewery, an ice plant, a soda bottling plant, and finally ended as an active industry still making ice. The museum chronicles the industrial and commercial history of Socorro's boom years, between 1880 and 1893.

Website has very sparse information about the museum. What does it offer?

The Society has as its purpose the discovery, preservation and dissemination of information concerning the Jewish experience in the Chicago area. The Society seeks out, collects, and preserves written, spoken, and photographic records, in close cooperation with the Chicago Jewish Archives, Spertus Institute of Jewish Studies. The Society publishes historical information, holds public meetings at which various aspects of Chicago Jewish history are treated, mounts appropriate exhibits, and offers tours of Jewish historical sites.

Though the Society does not have a museum, it does offer lectures and tours of Jewish historic sites in Chicago.

Organization, without a historic site base of its own. May still be worth including, though?
