It's amazing how much junk is floating around in the genealogy world. This is seen most obviously in collections based on gedcom files. Prime examples are World Family Tree, WorldConnect (rootswebs), Ancestral File and Pedigree Resource File. Search for a particular person, say one from the 1700s, and up will pop all kinds of garbage. Much of the garbage is recognizably copies of a few source gedcoms. Clearly there is wild name collecting going on by appending gedcoms without much examination. Ooooh, you have 50,000 names in your file, I'm impressed (and I'll be sure to stay away).
