Hi Brent! Thank you for joining our one world family WikiTree.
You generally can not delete a profile on the WikiTree. Your gift of time, information and sources to the WikiTree community are very much appreciated, but like any gift it is very difficult to take it back. Other people may have contributed information to the profile, and we do not want to delete their contributions because they are equally important and appreciated.
I see that you are the profile manager for Ruth's profile. You may want to change her privacy setting to protect her family connections to Private with a Public Family Tree. This will hide the details of her profile, but still provide a public family tree so that WikiTree can make DNA and cousin connections.
I hope this helps. Kitty
