Here is a link to a webpage on the website "Genealogy in St Louis" giving a history of St Louis Hospitals, Homes & Asylums. http://genealogyinstlouis.accessgenealogy.com/hospitals.htm
The website has a lot of information relating to genealogy in the St Louis area so you may want to also click on the link for the Home page and browse the website.
Here is a link to a City Directories page on my website. http://www.davernon.name/city_directories.htm
. For various years I have included pages from the directories listing the Asylums, Cemeteries, Churches & Hospitals.
