In the Y.K. Davening, we read about kohanim who kept trade secrets of the temple to themselves. One of these, Ben Kamtza, knew a way of writing gods name with four pens in one hand so all the letters complete at once.
I think the spelling is the same than Bar Kamtsa linked to Chorban but can't check now.
Are there any mephorshim that link the two personalities/families?
