Mortality Schedules are available at the National Archive branches and at Family History Libraries. Like the census they were done every ten years starting in 1850 through 1900. There was also one for 1885. Mortality schedules reported the names of persons who died preceeding June 1 of the census year. For 1850 for example the people listed would have died between June 1, 1849 - May 31, 1850. Heritage quest also sells CDs of the mortality Schedules. Their website is: http://www.heritagequest.com/ A book which you all might find very helpful is Your Guide to the Federal Census by Kathleen W. Hinckley, Published by Betterway Books of Cincinnati, Ohio. It not only has information on the about to be released 1930 US Census but also has information on the Mortality Schedules. The book was just released in February so it would probably be better to go through the Publisher to get it. I had a nightmare time ordering it through my local bookstore. It is soft cover, 275 pages. Cost is $21.95 US. I just got mine but it looks like it will be a handy resource for genealogists. Katheryn
