Well I'm not sure about that but I personally theorize that they amalgamated into the Sarutobi and Uzumaki clans both of which are alive and well. Granted we don't see much of the Sarutobi clan except for Asuma and Hiruzen but they are still strong if on,y because of Konohamaru and because of their decades old relationship with the Yamanaka, Nara, Akimichi clans. As for the Uzumaki clan while they villages demise is a shame the clan is still alive and well (after all two current Kage have Uzumaki blood in them and with Narutos children the Uzumaki clan will rise back to prominence even if it takes a rather long time to do so).
