In this case it makes sense to either merge the profile out of existence or reuse the profile to represent another person who really was named Chaloner.
Sometimes profiles are created for nonexistent people because people think they existed -- perhaps the person was documented in published genealogies, but has been determined to be a fabrication or a mistake. In those cases, if we eliminate the profile the person is likely to continue turning up ("like a bad penny"). In those instances, Melissa's advice is appropriate.
