The profile you linked to is a pre-1700 person whose profile is managed by a WikiTree project. The email address for the project is good. However, if you want to change the name, you'll need to give the Southern Colonies project some sources and some rationale for the name change. (The profile is unsourced.)
I see that you changed her first name from Margaret to Mary, and you changed her life dates. This makes me think that there could be two different people, and this might be a case of mistaken identity. Without sources, I can't tell.
