  We present results for masses of spin-1/2 and spin-3/2 double-charm baryons
in quenched lattice QCD, from an exploratory study using a non-perturbatively
improved clover action at beta=6.2. We have studied local operators and we
observe, after appropriate projections, a good signal for the ground states. We
also present results for single-charmed baryons and spin-splittings for both
double- and single-charmed states.
