Census Key: Mortality

1850 U.S. Census: Mortality Schedules for Hadley Township, Pike County, Illinois

The mortality schedules record the people who died in the twelve months before the census was taken.  In 1850, no distinction was made by township.  This database includes all of the deaths that occurred in the West Division of Pike County, including Hadley Tp.

In the “Remarks” section at the bottom of the schedules, the enumerator wrote the following assessment of his district’s health conditions:

There was some few cases of Cholera in my District in 1849. I know of no local cause for the same.  The Fever and Ague has been prevalent upon the River & [illegible] is becoming less so as the Country becomes settled.  The Water is impregnated with lime.  The Soil is a rich Loam it varies in depth from Six inches to Six feet.  My Division of the County is nearly equally divided into Timber Prairie and what is called here Barrens.  There are various kinds of Timber.  Black White and Red Oak.  Black & White Walnut.  Elm, Linn.  Hickory & Ash.
