A family in which all six siblings have PhDs.

Interesting that the Sutter Family of Hockey had six brothers play in the NHL and four of them went on to NHL coaching or GM duties.  But it wasn't a 100% hit rate like your family.  I'll say the hockey Sutters are more impressive as making the NHL is in most cases a more exclusive accomplishment.  Plus there was a seventh brother who apparently could have made the NHL but had other commitments.
