(I've tagged this with Charles Moorman's profile, because all three duplicate profiles for Mary Adams can be seen there)
To start, I don't know anything about these families, just that I was confirming a connecting line for the Global Family Reunion and noticed some duplicates. I've done a quick Google search hoping that someone cited sources in their trees for Mary Adams as the daughter of Robert Adams and Mourning Lewis, but nobody has. One of the Mary Adamses (Adams-4009) attached to Charles Moorman has parents attached. Another Mary (Adams-15570) has no parents linked, but the profile says she was the daughter of Robert and Mourning. The third Mary (Adams-11622) has no parents mentioned at all. All of the profiles for Mary have either GEDCOMs or Ancestry's Family Data Collection listed as sources.
