Family Search Labs is not the same as www.familysearch.org, although it is from the same organization, the Church of the Latter Day Saints. FamilySearch.org is still there and it was never really a research website, just a site with lots of different kinds of family trees uploaded and organized into various files, but still it was not original records; it also contains the Social Security Death Index and is a good site to get instructions on how and what records are available for research. Family Search Labs are original records which is what you would want to use to find actual proof of what one is researching.
Have you checked with your local Family History Center to see if they have microfilm of the death records you may be looking for? Also, have you checked the locations you last found the individuals, looking for birth, marriage, or death records to verify any of the families? The best place to start researching for vital records is at the County level and depending on where and what is available for your locations, you need to check also with what may be available at the State Archives for those same locations. And don't forget to check the Social Security Death Indexes, which are free at both Rootsweb.com and Familysearch.org. Genealogy is never totally free, there is always going to be some expense no matter what one does, but it helps if one can narrow down what they are looking for by looking through any indices available before one seeks to acquire the records one would need to order.
