Church of Jesus Christ of Latter Day Saints website "Family Search.org" Great free searches from Social Security Death records, Pedigrees, Family Websites, and you can choose the 1880 United States, 1881 British Isles, or the 1881 Canadian Census. Or search all. Good place to start out.
Ancestor's Website- from the PBS series.
Another sad link is to County Poorhouses which give detailed reports on the conditions for the paupers who lived there. Check out your county to see how it handled those less fortunate. Most have the 1857 report. Very sad. Some are much worse than others. Hard to imagine this could have happened back then.
