Last night I located a tree on ancestry.com that had a part of my family in it that I don't have much information on. I emailed the owner, and she wrote back this morning. In her message she linked me to a pilot search project at www.familysearch.org that had resources I haven't seen in one place before. More data from Alabama death certificates than can be gleaned from the index available through ancestry.com; it also has scans of Texas death certificates, and in both cases parents' names are given, when known. And it's available at no charge! AWESOME.
