The College of William and Mary is where Thomas Jefferson went to college along with other future US presidents and 16 signers of the Declaration of Independence. http://en.wikipedia.org/wiki/The_Col...lliam_%26_Mary

It seemed to go through extensive changes as not to seem entangling church and state. Unlike Harvard, it also looks like it was a public institution.

If I remember correctly both William and Mary were against the establishment of religion in England, Scotland and Ireland. http://en.wikipedia.org/wiki/William_and_Mary
