On January 10, 1921, a fire in the Commerce Department building, Washington, DC, resulted in the destruction of most of the 1890 census, to the woe of researchers ever since. For more detailed information, see Kellee Blake, "'First in the Path of the Firemen:' The Fate of the 1890 Population Census," Prologue: Quarterly of the National Archives, Vol. 28, No. 1, pp. 64-81 (Spring 1996), Part 1 and Part 2.
Some fragments of the 1890 census did survive, however, and they are very useful to researchers. The surviving parts include:
(1) General population census schedules
(2) Schedules of Union Civil War Veterans or their widows
(3) Oklahoma territorial schedules
(4) List of selected Delaware African-Americans,
(5) Statistics of Lutheran congregations
(6) Statistical information for the entire United States

I have some alternative information to the Wisser Family during this time period which I will post later when I locate it.
