Please read post 119. Icwhatudo has done the most research on this topic by far and he has not found any evidence that the grandparents donated anything to the school. What you remember seeing in the other thread may have been based in fact, or may have been someone else's speculation. If it is speculation (or in your case a memory of something you read), it should be clearly labeled as such and not posted as "fact".
If your post #44 is not true, then you need to tell the moderators to retract it.
