Karl Brown pointed out a parent conflict that emerged when duplicates around Margaret were merged.
Of the current two sets of parents, one of them apparently came from this MH branch: https://www.myheritage.com/research/collection-1/myheritage-family-..., which identifies Margaret's parents as John Fleming, Sr and Janet ‘Jennet’ Fleming. One problem with those parents is that the mother Janet Witherspoon would have been age 6 at the time of Margaret's birth (and a 15 year gap before the next child).
Joseph Fleming (Joseph Fleming) and (currently unknown) wife have dates which fit better.
