Still though...the implication from Michael's letter to his children at the beginning of the film was that when older, they were taken care of by their mother, who oversaw their education. From this one might assume that Michael and Kay did try to keep them (or at least Mary) sheltered from Family Business. So it could be that bastard cousin Vincent (another GFIII fabrication I won't even bother to go into) did not see Mary for many years prior to their 'bumping' into each other at that opening party. It would make sense that he didn't recognize the adult Mary after so many years.
