<p>Just parents? or do grandparents, etc. count as well?</p>
<p>I suppose they look at the "Stanford Affiliations" bit on the CommonApp supplement. As you have probably applied, I would suggest looking at that part of your application. It seems like they want to know a wide variety of affiliations that an applicant may have with Stanford, though i don't know how in depth they look at "legacy"....</p>
<p>grandparents generally count</p>
