Here is the answer to the quiz posted on 7/1/10. Go back and review it before reading the answer.
I was researching the 1890 Veteran’s Schedule (also called the Veteran’s and Widow’s Schedule).
Since the 1890 census was all but completely destroyed in a fire in January 1921 at the Commerce Building in Washington D.C., this 1890 Veteran's schedule is an alternative means of documenting veterans or widows of veterans from the Civil War and War of 1812 who were still living in 1890. The special census schedule still exists only for the states of Kentucky - Wyoming (the states alphabetically before "Kentucky" appear to have been destroyed). Officially this census documents only Union veterans. Some census takers apparently did not distinguish between Union and Confederate, however, so some surprising finds are possible.
