Bruce, try this step:
http://ancestry.custhelp.com/cgi-bin/ancestry.cfg/php/enduse...Unfortunately, Ancestry and RootsWeb are not very responsive when it comes to requests by email or snail-mail. You best option is to get into that account and delete it (or modify it) your self.
Also, Ancestry and RootsWeb will NOT remove information claimed to be "wrong" because their policy is that individuals have a right to be wrong. Ancestry or RootsWeb will not act as "gedcom police" checking the validity of your data submitted. You can actually claim that your mom and dad are the original Adam and Eve, making you some 10,000 years old (or so). Their policy is fairly straight forward: "people have a right to be wrong".
