The newly added Mary Margaret profile references an ancestry.com tree which has no sources whatever for Nathaniel, Mary or daughter Mary Margaret regarding any of their relationships.
Just on the face of it, it doesn't seem at all likely that Nathaniel and Mary McClure uprooted from Virginia, with several children, moved to Louisiana, had a daughter named Mary Margaret with other daughters named Mary and Margaret, and then moved back to Virginia to have more children.
Nah. As suggested, give the PM a couple days (at most) and delete the connections. No sources, no connection.
