Always read estate inventories carefully for potential references to real estate or other property that could suggest the deceased had lived in areas other than where they died. This 1904 estate inventory in Illinois indicated that Conrad Haase owned real property in Nebraska.
There may have been separate court action in Nebraska to handle the title to the property after Conrad’s death as his estate was probated in Illinois where he died. It is possible that the court action did not happen until years later, so records should not just be checked for the immediate time period around his death. Land records should also be referenced in Nebraska as well.
But do not just skip over those inventories of real estate. There could be clues buried in the verbiage.
