What is a reliable and completely free website that carries death records for peoples ancestery?
You can find Social Security Death records at familysearch.org, many burials at findagrave, a variety of information at genweb, sometimes birth, marriage and death records and a census project at http://www.us-census.org/inventory/ a forum for family names or locations at genforum (however, facts found on a forum need to be verified), and be sure you don’t post names of living people. Massachusetts sites have some great records online. Immigration records at the Ellis Island site. Many libraries have subscriptions to genealogy sites. WPA burial records have a number of records for Iowa. Illinois has some vital statistics indexed on the net. Random Acts of Genealogical Kindness can direct you to where to order some records and what is available. Be sure to return their favor by helping someone else. You can send for records at the National Archives, not free, but reasonable. There are many others.
