Mary Ann Robins (Foster) - DAR says Nancy married John

So this is probably NOT Nancy but is this Mary a daughter of this couple and did she really marry both men?
Also, I don't a Robbins or Robins in the cemetery listed

Here she is:
*Mary Foster was born circa 1748 and died after 1833 in Tennessee. She married Thomas Robbins on December 24, 1775 in Orange County. Thomas Robbins was born circa 1750 in Orange County and died before 1820 in Wilkes County. Another researcher states that Mary married (2) Lewis Hensley, married December 24, Orange County.
