When was this suppose to be there? I looked at the census records for 1910, 1920, and 1940 for the family. There was 6 households in 1940 in lake county. All the men seem to be involved in steel mill or metal. Nothing showing any farming.
Was this farm a private family or a larger company farm? If you have the time might contact didier farm in buffalo grove. They were once one of the largest in the area and might know a little about them( and the elders are farming historians types) if it was after 1940 census.
