Thank you for your response. I may not have been clear in my query. I am seeking information on the parents, Joseph Dixon and Susan Jackson. The 1890 census debacle is a stumbling block, as that would have been the first census in which they would appear following their marriage. By the time the 1900 census was taken, they were both dead (cause unknown). As a family unit, they do not appear on any existing census record. Both Carrie and Victor appear in the 1900 census in St Louis--Victor with his adoptive parents (as you posted), and Carrie in the Orphans Home. I have not been able to find John in the 1900 census (he went to live with an unnamed grandparent according to family history), nor have I found any trace of Rose. A quick search has not revealed any leads in the 1880 census for either Joseph or Susan, although I have begun a more exhaustive search.
