The following record collection in Ancestry Library Edition (Ancestry LE) covers deaths recorded in the Death Registry Books for St. Louis during the period August 1850 through December 1902:
St. Louis, Missouri, Death Records, 1850-1902
Statewide registration of deaths was not required by law in Missouri until 1910—only about 60 percent of St. Louis City deaths were recorded prior to that date.
It is possible to search using any of these parameters:
First & Middle Name(s)
You can of course search for an individual of interest, but it is also possible to do a general search of these records for pauper deaths. Each of the following searches produces numerous results (case does not matter):
Cemetery: potters field (Exact) 148 hits
Address: poor house (Exact) 329 hits (some of these results are for places other than St. Louis)
These searches should prove of great interest to genealogists, students, and local historians.
You can use Ancestry LE at Central Library or any of our branches.
