Jessica, I see that your McFatters are in Louisana and Mississippi, a search at GenealogyBank pulled 35 hits for those states plus North Carolina McFatters (pre 1880) but none of them are death notices or obits. (Though you can find death notices in that range from time to time in the newspapers.)
Again the search engine at GenealogyBank is poor, though they are improving the site continually. Example: I have someone named "Royal White" who married into my family. To find anything related to him pulled up hundreds of clothing ads, and there was no way to exclude them from the search.
