Blanche, the least controversial -- and most effective, I think -- way to go about this is to take the profile for which these six people are the ancestors, and right above ==Sources== create a section called ==Research Notes==
Type under Research Notes, "The following ancestors of XX are being researched for addition to WikiTree." Then under that create subsections for the names of the six people you have in mind:
In each section, gather all the sourced information you can find. This is work that would have had to be done once the profiles for these people were created, but here you can do it BEFORE their profiles are created.
Certainly at the beginning add information you find on ancestry or geni or my heritage but give its source <ref> Ancestry.com [the url link where you found it] </ref> Those aren't very good sources, but they often provide information that give you research clues, which if you keep poking around may lead to really solid sources.
This way, the barriers we have put in place to keep WikiTree from getting more badly researched profiles don't get in your way, and you're doing the solid work that will make these profiles ones you're proud of.
And when they're well sourced, it will be totally simple for someone who can, to just copy everything you have under ===Peter Dent=== into a new profile.
Research first; profiles second. This is basically what others are telling you, but here is a way to do it!
