There was a George Just with his family at LaSalle, LaSalle County, Illinois in the 1880 U.S. census which you can search online at: http://www.familysearch.org Select the census link on the left side of the home page, and select the 1880 U.S. census in the top box of the next page. Ask for Just in Illinois, and then select LaSalle for the county. This has been very helpful to me, and was placed online in October by the LDS church. Adele/Seattle
