You have diligently recorded (in a CensusTools spreadsheet of course!) all of the available information from the U.S. federal censuses for your ancestors, but you still have some gaps. Some of the federal records you were counting on were unreadable, and just when everyone in a family was finally listed by name in 1850, there’s that 2g-grandfather who somehow didn’t get enumerated. You’d love to be able to pinpoint when your paternal g-grandfather and his family moved from New York to Iowa, but the 10 year gaps between federal census returns doesn’t narrow it down much for you. What’s a researcher to do?
1890 Census Record Loss: Most of us have experienced the frustration of researching our grandparents and great grandparents through the years, only to find a huge gap in available data due to the loss of the 1890 census. Four of my great grandparents immigrated to America in the 1880’s and the 1890 census would have provided their first census records as Americans.
