There are no Jedi that we're told about. But countless Jedi were on missions, and I doubt all of them were killed by Clone Troopers. Even Obi-Wan and Yoda acknowledge it, when they change the broadcast message to tell any other Jedi to stay away from the temple. Not to mention we only see a few Council members killed, not all.

I believe in the books, there's mention of other Jedi who survived and tended to the Jedi holocrons. edit: And I am aware that Yoda tells Luke he's the last of the Jedi. That is, however, 20 years later. Anyone else who had survived the initial purge could have been caught later, or died of age, or whatever.

And by the way, Jedi is the plural of Jedi.
