I see nothing in Overview that shows him having had a first wife, which would necessarily be the case since Rose died after Aaron.
I see no marriage to a Rose Stanfield in look-up on FamilySearch:

Exactly right, Ken. No sources for a Mary marrying Aaron. It is only linked from a standard do it yourself family tree site. I am secretary and one of three chief genealogists active with the Mendenhall Family Association. Our website at mendenhall.org shows that Aaron born 1690 only had Rose Pierson married to him. That Mendenhall family tree of nearly 100,000 profiles is the Pedigree club for the family. Besides Rose was the mother of all the children. There are innumerable sources for that fact. But a Mary has no sources. We have Mary Stanfield as the wife of Aaron's son Elijah, but even that Mary Stanfield has no sources and only appears in many family trees. In order to not be seen as hypocritical, I believe I was the one who added Mary in there as the wife of Samuel. I just thought that Samuel needed a mother and Elijah needed a wife. But that's just me.
Error of mine again. I see now that I only connected their son Samuel to the couple a few years ago because I was doing first hand research into that part of the Aaron line as well as being helped by some descendants of Aaron although they did not know it apart from the dna evidence they had obtained. The link was through John Mendenall born 1791 (that's right no h in his name, done on purpose)
